Production on the Marvel Studios trilogy-maker Iron Man 3 has been delayed after an injury involving star Robert Downey Jr. recently.

The injury isn’t serious, as apparently Downey Jr. hurt his ankle performing a stunt on the movie, which is directed by Shane Black (Kiss Kiss Bang Bang).

There’s a lot of speculation as to what the plot for Iron Man 3 could be. It is believed that the film could be based on the Extremis storyline, which centers on a technologically based virus that could turn any normal human being into tech-based super soldiers.

No doubt there will be some sort of confirmation when Marvel Studios President Kevin Feige takes the Hall H center stage at the San Diego Comic-Con later this month. But before we hear from Feige or get a confirmation of a synopsis, we have a piece of concept art from the movie that may confirm the Extremis storyline. Check it out below.

After weeks of non-stop casting announcements and analysis of its possible plot, the Walt Disney Pictures and Marvel Studios film Iron Man 3 has commenced principal photography in Wilmington, NC. We have the first behind-the-scenes image from the production. You can check it out here below.

The film’s plot is reportedly based on “Extremis,” a six-issue story arc from Marvel Comics’ The Invincible Iron Man written by Warren Ellis and drawn by Adi Granov, which would introduce nanotechnology into the character’s ongoing adventures. Shane Black is directing Iron Man 3 from a screenplay he co-wrote with Drew Pearce. Returning to the cast are Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, and Jon Favreau (a good indication that not much bad blood exists between Favreau, who directed the first two Iron Man films and had originally planned to direct the third and complete his trilogy, and Marvel Studios). New to the cast are Rebecca Hall (Frost/Nixon) and Andy Lau (Infernal Affairs), and playing the heavies of Iron Man 3 are Guy Pearce, Ben Kingsley, James Badge Dale, and Ashley Hamilton.

It’s not like we didn’t see this coming, but its still nice to get a confirmation at least. When it was announced that Ben Kingsley was cast as a villain in the Shane Black-directed Iron Man 3, many had speculated that he would be playing the villainous Mandarin. Of course Disney and Marvel denied these rumors and said that the villain would be behind a nefarious plot of releasing a nanobot technology-based virus.

Latino Review has confirmed that Kingsley will actually be the Mandarin, and that there is a power structure that will make the Iron Man 3 story the most complex in the Marvel Cinematic Universe. Again Disney and Marvel continue to deny these rumors, but as cameras start to roll today, the site said that can confirm that the Mandarin is indeed in the movie.

Earlier today it was reported that Jessica Chastain had opted not to take on the “sexy scientist” role she was said to be up for in Iron Man 3. Not wasting any time, it looks like director Shane Black and company had another actress on stand by.

According to sources, Rebecca Hall is now in negotiations to play the character Chastain was lined up for. Apart from the brief description indicating that the character would be an attractive scientist type who’s just as smart as Robert Downey Jr.‘s Tony Stark character, all that’s known is that this will be a supporting role. Gwyneth Paltrow‘s Pepper Potts character is the movie’s female lead.
