Too Many Irons In the Fire: Though Robert Downey Jr. is signed on for an Iron Man sequel and an Avengers film that will group together Marvel heroes including Thor, the Hulk, and Captain America, the actor is starting to sound a little concerned about the latter property. “If we don’t get it right, it’s really going to suck,” he told MTV. “Nothing that happened in Iron Man is really outside the realm of possibility. Once you start talking about Valhalla and supersized super soldiers and jolly green giants, it warrants much further discussion.” [MTV]
