Here are some notes from the Iron Man 2 press conference that took place in LA today. It was attended by producer Kevin Feige, director Jon Favreau, writer Justin Theroux, Robert Downey Jr., Gwyneth Paltrow, Don Cheadle and Mickey Rourke.
Some background about the film was revealed through questions from the press as well as an interesting possibility about Scarlett Johansson's character in the film.
Kevin Feige stated that Iron Man 2 takes place before Incredible Hulk. That's already been talked about but he confirmed it. He also said there's a clue towards the end of Iron Man 2 that indicates that (I've seen the film and I missed it).
Justin Thereoux said that it was a "heavily improvisational set" when asked about how close to the script the production was. A lot of modifications were made on the fly due to the nature of the cast.
Don Cheadle said that the Mark II (sliver) armor was actually metal as opposed to the familiar Mark III worn by Robert, which was fiberglass. That made it quite a bit more uncomfortable and hard to work in.
When asked about the inspiration for Mickey Rourke's character Jon Favreau stated that Viggo Mortensen in Eastern Promises was an inspiration for Rourke's character. He wanted to take a character who in the comics wore tights and had a purple feather sticking out of his head in the comics and make him "technical."
Favreau also said that he tried to keep the story simple and not have the film suffer from "villainitis". He brought Rourke and Rockwell together early so their story would be more of a single intertwining story - same with Scarlett and the Pepper/Stark relationship. That way there weren't 5 different arcs going on.
One thing that Kevin Feige was very clear about is the fact that a Black Widow spinoff starring Scarlett is a definitely possibility.
Finally when asked about the DVD release, Jon Favreau stated that the Iron Man 2 Blu-ray will have commentaries in addition to a ton of extra features (there were no commentaries on the first Iron Man Blu-ray).
