In the Iron Man 3 thread, I mentioned a "Playlist" podcast
with info on IM3 that I couldn't access at work. Now that I'm home, I listened to the whole thing, and it turns out that there is all sorts of future Marvel movie info.
The first 20 minutes is about DC movies and JLA. The Marvel stuff begins at 21 minutes.
There is a ton of info and casting speculation and possible spoilers, but in brief...
Iron Man 3 to feature Mandarin and Radioactive Man as the villains and Ant-Man is apparently going to be introduced in the post-credits sequence. Gwyneth Paltrow will have a reduced role in IM3. Apparently, Edgar Wright would like Simon Pegg to portray Hank Pym, in preparation for a 2014 release of Ant-Man. (An aside-- how do YOU pronounce "Pym"? I always pronounced it like "dim", but in the podcast, they are pronouncing it like "dime".)
Kat Denning's Darcy will NOT be in Thor 2. Expect appearances from the Enchantress, Executioner and, apparently Dr. Strange (?), who seems to be a colleague of Jane Foster. (The Eye of Agamotto was in Odin's throne room in Thor! Was this planned that far in advance?)
Cap 2 is still being written, but Arnim Zola will be in the movie along with Bucky/Winter Soldier, and presumably the Red Skull. SHIELD will play a big part, with Fury, Widow, Hawkeye and Hill all having roles. Also possibly an appearance by William Hurt as General Ross! Also, possibly the return of Hayley Atwell as Sharon Carter in the modern day!
Talk of Heroes for Hire or another Hulk film for 2014. Black Panther may appear in the Hulk movie. Joss Whedon is intertested in writing the Hulk sequel for Drew Goddard to direct. The guy who played Sam Sterns/the future Leader is signed for more movies.
RDJ's contract runs out after Avengers 2, not Iron Man 3, but he is in re-negotiation contract talks.
