Will the cast from the film lend their voices to the game?

I was wondering if the cast from the film will lend their voices to the game? I know that Robert Downey Jr lend his voice of Tony Stark to the first Iron Man game. I was wondering other fellow castmembers such as Gwyneth Paltrow, Don Cheadle, Samuel Jackson, Mickey Rourke. Scarlett Johannsson, and Sam Rockwell will also voice their fellow character respectively.
