Marvel movie news has been coming out fast this week. First, we reported some interesting tidbits on Iron Man 3 casting and a possible Ant-Man cameo. Then, earlier today, we shared the bombshell news that a Guardians of the Galaxy film is heading to theaters in 2014.

If that weren’t enough to chew on, though, we have a few more Marvel items to share, including some news on Thor 2 casting, a big Iron Man 3 action scene, Edgar Wright’s Ant-Man test footage, and a first look at the logos for upcoming Marvel movies. Read on for our Marvel movie news round-up.

Dr. Selvig to Return in Thor 2

Stellan Skarsgard has confirmed that he will reprise his role as Dr. Erik Selvig in Thor 2. In an interview with Hey U Guys! for the Norwegian film King of Devil’s Island, Skarsgard said that he would join the production when it starts filming in August.

In addition to Skarsgard, Thor 2 will also see the return of Idris Elba as Heimdall and Jaimie Alexander as Sif, among other key cast members. One notable exception: Chuck‘s Zachary Levi may replace Josh Dallas as Fandral, one of Thor’s trusted Warriors Three.

Iron Man 3 Could Feature Earth-Shaking Action

Recently, a handful of behind-the-scenes photos from Iron Man 3 hit the social news-sharing site Reddit showing construction on the now-familiar set of Tony Stark’s mansion.

As you can see from one of the photos below (courtesy of Latino Review), the pictures themselves were not altogether exciting. However, the follow-up rumor (also courtesy of Latino Review) was.

According to a tipster, the entire mansion set is “actually built on a very sophisticated gimbals system.” To save you a quick Google search, here’s the definition of a gimbal: “A device consisting of two rings mounted on axes at right angles to each other so that an object, such as a ship’s compass, will remain suspended in a horizontal plane between them regardless of any motion of its support.”

Typically, gimbals are used in film to simulate sudden motion. By now, you should probably get the point, but just in case, LR’s tipster spells it out: “This is a set up for total destruction. How do you fight a superhero? Hit him in the most sacred place….his home. Villains of ‘Iron Man 3′ hit Tony Stark and hit him hard enough for his mansion to fall into the Pacific Ocean.

Will it play out exactly like that? Maybe not, but it’s probably a safe bet that a big set piece in Iron Man 3 will take place at Stark’s home. What a shame, too, since he probably just got done redecorating from his fight with War Machine in Iron Man 2.

Marvel Sequel Logos

Marvel has a bunch of films on its slate, but most of them won’t come out for another two or three years. Naturally, that won’t do for all of us fans who are eager for any scrap of information about the new movies. Luckily we have new logos (via BadTaste.it) for Iron Man 3, Thor 2, Captain America 2, and The Avengers 2. Okay, it’s not much, but it’s something!

Ant-Man Test Footage

We already mentioned the possibility of Ant-Man appearing in some capacity in Iron Man 3, but perhaps fans will get a chance to see the insect-themed superhero even sooner than that.

The Hollywood Reporter has the news that Edgar Wright “spent just under a week shooting footage for a reel that will be used to test out the potential look and tone of his movie, as well as to decide how convincing Ant-man’s powers look onscreen.

This is fairly common practice for movies that require significant special effects, so it doesn’t mean that fans should expect to see anything jaw-dropping. In fact, they may not see anything at all. Typically, test screenings aren’t meant to be seen by more than a handful of people.

However, the fact that Wright finished the test shoot just in time for Comic-Con 2012 leaves the possibility that Marvel will show off the footage to fans during the studio’s perennial Hall H presentation. We can only hope right?

The Avengers Blu-ray Trailer

Let’s go out with a bang, shall we? If you watched and loved The Avengers (and really, who didn’t?), you’re probably going to pick up the movie on Blu-ray. However, just in case you needed more convincing, check out the newly-released Blu-ray trailer for the film below:
