Considering Black hasn't had any work since
Kiss Kiss, Bang Bang came and went without much fanfare (a shame, since it might be the best film he's made) in 2005, I'll take this with a grain of salt.
That said, I hope it's true. He's proved that he can get great work out of Robert Downey, Jr., and his breezy, comedic touch is exactly what
Iron Man needs more of.
