RDJ1Robert Downey Jr now has 2 appearances as Iron Man done and will be teaming up with Captain America, Thor, and other heroes in The Avengers in 2012. How does such a respected actor prepare for a huge role? Research.

Celebrity photo site JustJared published photos of Downey at a comic book store grabbing issues of The Avengers as well as Iron Man. Here he is standing behind some dude in a Dharma Initiative shirt waiting to ring up his selections.

Comic Book movies have been the rage for the last decade and theres been a lot of actors who’ve done well in them while still admitting they don’t read comics. Its pretty nice to see Downey not only reads, but goes to his local comic store and buys books himself rather than having an assistant do it or have Marvel send them over directly.
