Marvel Studios has given fans a belated Christmas present with a new holiday card from Iron Man 3, with Robert Downey Jr.'s Tony Stark admiring the snow falling down around him. Take a look at this unique Christmas card, then read on to see what the actor had to say about this superhero sequel.

Last month, producer Kevin Feige revealed Iron Man 3 is not a "serious movie." Robert Downey Jr. revealed in a recent interview that director Shane Black wants a "dark feel" for this follow-up, while going back to the Marvel comic book roots.

"I think Shane has gone for a dark feel in this movie. It's a lot grittier and goes back to its comic-book roots. It's shaped into a really special movie - and Shane as been instrument [sic] in that."

Robert Downey Jr. also spoke about the villainous Mandarin, played by Ben Kingsley.

"I always think there's something more terrifying about a villain who's a genius, as opposed to just relying on strength or ability. We all know what a fantastic actor Ben Kingsley is, and he pulls off the evil genius with real terrifying results."

He also spoke briefly about doing all of his own stunts, and commented on the ankle injury he suffered on the set back in August.

"I've always said that while I'm physically able, I want to do all my own stunts in the movies that I make. I want the audience to sit there, thinking, 'was he really stupid enough to attempt that?' I actually hurt my ankle in a stunt and filming was shut down for a few days."
