This December, the Skywalker saga at the core of the Star Wars franchise will be coming to a definitive end. Fans have been following the story of Luke and Leia’s bloodline for over 40 years now, so a lot is riding on the big finale.

Long before J.J. Abrams rebooted the saga for Disney, and long before George Lucas divided his own fan base with a trio of prequel movies, we had the original trilogy. Lucas came to 20th Century Fox as a young man with an idea for a weird little space movie – the fourth part of a six-part epic – and somehow managed to get it funded. But he faced an uphill battle, as the studio had very little faith in the film and even tried desperately to bury it. It was all but guaranteed to be a failure.

And then something incredible happened: it struck a chord with audiences across the world. By the second or third week of its release, people were lining up around the block to watch it for the tenth time. Two highly anticipated sequels followed and the rest is history – the Star Wars phenomenon continues to this day. It’s stronger than ever, actually. Here are 25 Crazy Things Fans Didn’t Know Behind The Making Of The Original Star Wars Movies.

The Producers Wanted A Movie Star To Cameo As Darth Vader

At the end of Return of the Jedi, when Darth Vader is unmasked and we see his true face for the first time ever, he’s played by Sebastian Shaw. Who? Exactly. Originally, the producers wanted a huge star like Laurence Olivier to cameo as Vader in the unmasking scene.

However, during story discussions, they scrapped the idea as they realized it would lessen the impact of the scene. It was probably the right call. It would take us out of the scene to have to say, “Oh, look, it’s Laurence Olivier!” This is the moment in which Anakin Skywalker looks upon his son with his own eyes for the first time. That’s important enough without a big movie star.

Lucas Didn’t Know Leia Was Luke’s Sister At The Time Of Their Kiss Scene

Everyone likes to joke about the incestuous overtones of The Empire Strikes Back’s kiss between Luke and Leia, since they were revealed to be twins one movie later. However, while George Lucas had plotted out the rough outline for all six movies from the start, he hadn’t ironed out all the details and was still making some things up as he went along.

The exact plot points in each movie were still being decided in each subsequent writing process. When they shot the kiss scene, he still hadn’t figured out that Leia was Luke’s sister. Thus, it’s not totally weird.

Harrison Ford Wanted Han To Be Written Out Early In Return Of The Jedi

We finally saw Han Solo breathe his final breath after being slashed down by his own son in The Force Awakens, but Harrison Ford actually wanted the character to meet his end much earlier. During the production of the original trilogy, he never signed on for more than one movie at a time.

That’s why Han was frozen in carbonite at the end of The Empire Strikes Back – in case Ford didn’t sign back on for the third movie. He did, but he really pushed for a scene where Han is terminated early on in the story. Lucas refused, because Han needed to complete his character arc for the trilogy.

Emperor Palpatine Was Originally Played By A Woman With Superimposed Chimpanzee Eyes

In the prequel trilogy and the Special Editions of the original trilogy (and in the upcoming The Rise of Skywalker,) Emperor Palpatine is played by Ian McDiarmid. However, in the original cut of The Empire Strikes Back, Palpatine only appears in a hologram scene and his character wasn’t fully fleshed out yet.

Back then, he was played by a female actor named Marjorie Eaton with chimpanzee eyes imposed on her face to give her a creepier look. It did successfully create the iconic Palpatine look, but future movies would just use makeup effects.

Mark Hamill And Carrie Fisher Didn’t Use Stunt Doubles In The Swinging Scene

The latest Star Wars movies – especially the prequels – can get around dangerous stunt work with CGI. But back in the late ‘70s and early ‘80s, every stunt had to be done practically (unless it involved miniatures). Most actors would just use a stunt double.

However, in A New Hope, during the Death Star escape, there’s a moment where Luke and Leia swing across a giant chasm. Mark Hamill and Carrie Fisher didn’t use stunt doubles in this scene and actually performed the stunt themselves. In fact, they nailed it in one take.

Return Of The Jedi Was Filmed Under The Title Blue Harvest

Family Guy fans will be familiar with this fact, because Blue Harvest was used as the title of the show’s special episode parodying Star Wars. It’s a common practice now to use a fake title during the production of a much-anticipated blockbuster like The Avengers or The Dark Knight to avoid fans finding out where they’re shooting and leaking plot details from the set or interrupting filming.

But back then, it was a novel idea thought up by George Lucas to protect the set of Return of the Jedi. Blue Harvest is the most well-known fake working title used by a Hollywood production, because it started the trend.

Harrison Ford And Carrie Fisher Were Hungover While Shooting The Cloud City Scene

If you look closely at Han and Leia in the scene in The Empire Strikes Back where they arrive at Cloud City, you’ll notice that they look a little dazed and tired. That’s because they both had terrible hangovers from the night before.

Despite the fact they were in the middle of shooting a Star Wars movie, Harrison Ford and Carrie Fisher spent the night partying until six in the morning with the Rolling Stones and Monty Python’s Eric Idle – and then they had to shoot the Cloud City scene. It’s not like you’re going to turn down an invitation to party with Eric Idle and the Stones, even if you do have work in the morning.

George Lucas Wasn’t A Particularly Hands-On Director

A New Hope was the only movie in the original trilogy that George Lucas directed, and according to the actors, he wasn’t very attentive to their performances. Some directors, like Martin Scorsese, watch their actors intently and provide detailed feedback.

Scorsese reportedly even keeps an eye on all of his extras and gives them specific notes between takes. However, Lucas just said either “faster” or “more intense.” At one point during filming, Lucas lost his voice, so the cast gave him a board with just those two phrases on. It worked a charm!

Return Of The Jedi Originally Had A Much Darker Ending

After the downbeat cliffhanger ending of The Empire Strikes Back, it was a relief when Return of the Jedi ended the trilogy on a positive note – but it almost didn’t. In early story discussions, George Lucas suggested taking the plot in a much grimmer direction.

Lucas told his co-writer Lawrence Kasdan, “Luke takes [Vader’s] mask off. The mask is the very last thing – and then Luke puts it on and says, ‘Now, I am Vader.’” Kasdan replied, “That’s what I think should happen.” In the end, and probably for the best, this was scrapped in favor of the happier, more hopeful ending we got.

The Actors Only Stopped Goofing Around When Alec Guinness Was On-Set

According to Harrison Ford, he and Mark Hamill would goof around on the set of the original Star Wars movie, but only on the days when Alec Guinness wasn’t on the set. If Guinness, a behemoth in the acting community, was around, Ford and Hamill acted more professionally.

To be fair, back then, the Star Wars universe was completely unknown. It was up in the air if it was going to be a success or not, and the odds were against that. The actors were uttering words like “Jedi” and “lightsaber” and “Death Star,” which were nonsensical back then. They probably figured they might as well have fun while they were doing it.

The Lightsaber Sound Effect Was Achieved Creatively

Sound designer Ben Burtt is famous for using unusual items to create sound effects. For example, he got the sound of the lid being removed from the Ark of the Covenant from sliding the lid off the back of a toilet. In the Star Wars trilogy, he created the sound of a lightsaber by mixing the hum of an unused 35mm film projector and the feedback that comes from moving a stripped microphone cable past a TV set.

There are endless digital archives of the sound effect now that there are countless toys, video games, and TV shows it’s used in as well as the movies, but it all stems from that.

George Lucas Tried To Get Some Big-Name Directors To Helm Return Of The Jedi

While George Lucas directed every prequel movie from his own scripts, he only directed the first movie of the original trilogy. Irvin Kershner took on The Empire Strikes Back, while Richard Marquand handled directing duties on Return of the Jedi. But before Marquand was hired, Lucas tried to get some A-list directors on board.

He first asked his friend Steven Spielberg, who declined because Lucas was producing the movie outside the Directors Guild of America, before courting horror directors David Lynch and David Cronenberg, who both turned him down in favor of their own projects.

Harrison Ford Improvised The Intercom Exchange In A New Hope

Star Wars: Han Puts His Feet Up in the Death Star

Remember the scene in the original Star Wars movie in which Han Solo is on the Death Star, talking over an intercom system? He ends up shooting to intercom and saying, “Boring conversation anyway.” Apparently, Harrison Ford decided not to learn his lines for that scene and instead improvised it on the day, so that it would seem more spur-of-the-moment.

It’s rare that actors get to ad-lib in a Star Wars movie, since each one goes through a rigorous story-breaking process that ends with a pretty rigid and air-tight script, but this resulted in a nice touch of authenticity, so maybe it should be more common.

The Dagobah Swamp Scenes Were Partly Shot In George Lucas’ Pool

The Dagobah sequence in The Empire Strikes Back is one of the most important in Star Wars history. It introduced audiences around the world to Yoda, and also resulted in Luke being trained once and for all as a genuine Jedi. Obi-Wan had given him some pointers, but this was where he truly grappled with his Force powers.

At one point during the Dagobah scene, R2-D2 is consumed by a monster and then spat out into the swamp. He splashes into the water and starts to sink. This might look like a genuine swamp on-screen, but it was actually filmed – at least partly – in the swimming pool in George Lucas’ backyard.

Han Solo Is Frozen In Carbonite With A Different Shirt

When Han Solo is frozen in carbonite in The Empire Strikes Back, we see him in a white shirt with folded-over collars like what a chef would wear. But in his frozen form, as we see him for the rest of that movie and the beginning of Return of the Jedi, he’s wearing a regular shirt with a narrow, low-hanging V-neck.

This was a result of a lack of communication between the people dressing Harrison Ford for the freezing scene and the people making the carbonite prop. An important lesson was learned.

The Jawas’ Sandcrawler Was Mistaken For A Military Vehicle

While the original Star Wars movie was shooting in Tunisia, the Jawas’ Sandcrawler was parked a little close to the Libyan border – close enough that the Libyan government feared it was a military vehicle, and that military action was imminent. After some wacky political misunderstandings, the Tunisian government had to politely ask Lucas to move the Sandcrawler.

While Lucas and his crew were shooting the scene where Luke and Uncle Owen buy Artoo and Threepio, and the Jawas try to rip them off with a droid that has a “bad motivator,” some politicians were in a frenzy as they prepared for what they thought meant a coming war.

Return Of The Jedi Was The First Movie To Be Given THX Certification

We all know the THX logo that appears at the beginning of some blockbusters and blows out your eardrums with a slowly rising instrumental sound. These movies have been awarded “THX Certification” by Lucasfilm, and they come with a set of instructions for theaters, claiming each screening room “must be acoustically neutral – on-reverberant – to prevent sonic reflections from muddying dialogue; and [their] sound systems must reproduce substantial deep bass throughout the hall.”

The very first one was Return of the Jedi, and the certification was born when Lucas couldn’t figure out what was wrong with the movie’s audio. He realized it wasn’t an issue with the print, but rather the theater he was screening it in.

The Alien Skeleton On Tatooine In A New Hope Is Still There

In one of the scenes set on Tatooine in A New Hope, C-3PO is walking through the desert and a giant alien skeleton can be seen behind him. This skeleton was later identified as belonging to a greater krayt dragon. After the crew finished shooting in Tunisia, no one removed the skeleton and it was just left there.

Years later, when the same crew returned to the same area of Tunisia to shoot Attack of the Clones, they found that the skeleton was still there – and it still is today. Go and check it out!

Steven Spielberg Was The Only One Of George Lucas’ Friends Who Thought Star Wars Was Any Good

Star Wars Trivia Spielberg Empire Strikes Back

Upon completing his final cut of the first Star Wars movie, George Lucas screened it for all his director friends, like Francis Ford Coppola and Brian De Palma. He’d faced a disturbing lack of faith from the studio, the crew, and even some of the cast at this point.

And then his friends tore the movie apart. De Palma called it the “worst movie ever.” It can’t have been great for Lucas’ spirit. Spielberg was the only one of the bunch who thought it was good and would be successful – a beacon of hope, kind of like Luke in the movie.

George Lucas Hated Han Solo’s “I Know” Line

Han Solo gets frozen in carbonite in Star Wars The Empire Strikes Back.

Towards the end of The Empire Strikes Back, right before Han Solo is frozen in carbonite and taken to Jabba the Hutt’s palace, Leia tells him, “I love you,” and Han simply replies, “I know.” It’s one of the most iconic moments in Star Wars history. But George Lucas hated the “I know” line.

Harrison Ford came up with the line himself and kept pushing for it, but Lucas thought it would be unsuitable for the film’s audience. Of course, Ford was right – it’s totally in character for Han and is remembered by every one of the saga’s fans.
