Robert Downey Jr.

First, the good news: Robert Downey, Jr. has agreed to star in 'Iron Man 4' for Marvel! Considering everything he has been saying over the past year or so - essentially that he can't imagine an 'Iron Man 4' ever happening - that's a major step in the right direction and a huge win for Marvel Studios. But...Downey's agreement has come with one rather large condition. That his old friend, and current member of the Hollywood blacklist, Mel Gibson be allowed to direct.

Robert Downey Jr. is back for more zany adventures in 'Sherlock Holmes: A Game Of Shadows,' the sequel to the uber-popular 2009 action-comedy. Based on the trailer, which hit the Internet on Tuesday, 'Shadows' looks to be even more action-packed than its predecessor, with guns, explosions and, um, Downey Jr. in drag.
