When it comes to movies, the most important characters are generally those that are considered to be the leads. Whether they be the titular character; such as characters like Superman, Batman, Bridget Jones or Mary Poppins, or characters who are clearly the star; like Marty McFly, Freddy Krueger, Annie Wilkes or Ellen Ripley - it's generally very obvious which character is the most important in any given movie.
But that's not always the case. Looking back on certain movies, characters who weren't given the top billing are often a lot more important than you might think. Whether they were integral to the plot, or were merely being introduced for a bigger purpose that you weren't aware of at the time, you might be surprised at just how important certain characters are - even, in some cases, some incredibly minor ones - and that's what this video is all about.
Nebula in Guardians of the Galaxy
Guardians of the Galaxy was all about the titular team. Gamora, Drax, Groot, Rocket and, in particular, Star-Lord stole the show. And you'd be forgiven for thinking that they'll be the most important characters going forward - but that's not the case at all.
Karen Gillan's Nebula wasn't even the secondary villain - Ronan and Thanos were the two most important villains in the movie - and Nebula could easily have been considered by audiences to be gone for good, given her exit scene at the end of the movie. But that's far from the case. Not only will she switch sides to join the titular team in the 2017 sequel, but she could also be a key character in the Infinity War movie saga. In the comic books, it was her that removed the Infinity Gauntlet from Thanos' possession and returned reality to how it was before - don't be surprised to see that happen on the big screen.
Blind Al in Deadpool
Just like in the comic books, Ryan Reynolds' Deadpool shares a house with an elderly lady called Blind Al in 2016's live action movie based on the character. In the movie, Al is a minor character, only appearing in a small number of humorous scenes and, unlike in the comic books, Deadpool is relatively nice to her.
But Al is a much more important character in the wider world of Deadpool lore. Not only did Wade Wilson let her go, after having been paid to kill her, in his pre-Deadpool days, but she also acts as his guide, with the intention of keeping him on a somewhat heroic path and helping him to better himself. Moreover - and rather excitingly - she actually potentially ties the Deadpool movie and, subsequently, the entire X-Men movie franchise, to the MCU, as she was an old girlfriend of Captain America's back in the days of World War II!
Harley Quinn in Suicide Squad
No matter how you look at it, Harley Quinn was undoubtedly one of the most important characters in the Suicide Squad movie, but did you truly realise just how important? We doubt it very much.
Harley's inclusion is the main reason that two other massive characters in Batman and The Joker were able to be included, which is a huge deal. Also, as a crazy sociopath bordering on the line between hero and villain, she's a bona fide rival to Fox's hugely popular Deadpool. She's also a marketing gold-mine, given the merchandise and costumes she will sell. And, most importantly, she's opened the door for more female leads in comic book movies, which have been sadly and sorely lacking up until now.
