Edward Norton says Brad Pitt "can't sing", so he won't be starring in a musical version of "Fight Club."

Edward has heard rumors a musical version of the hit 1999 film could be on the cards, but says neither he nor Brad - who played the two lead characters in the movie - will be participating.

The 39-year-old actor said: "This has been floating around for a while. I've seen different notions of it. I doubt it'll be me and Brad. I know Brad can't sing."

Although he has ruled out starring in the musical, Edward is intrigued by reports Nine Inch Nails star Trent Reznor will be penning the music for it.

He said: "Reznor would be about the right vibe for it, I guess."

Edward also refused to confirm rumors he will be appearing in "The Avengers" or a sequel of "The Incredible Hulk," insisting movie fans will probably find out if he has landed the parts before he does.

He told MTV: "I really couldn't say whether I will be reprising the Hulk. The minds of Marvel are sometimes opaque. I won't say obtuse, but opaque. I don't have any idea what they want to do. This notion of connecting the Marvel characters - who knows where they'll go."

"I really actually have no information about 'The Avengers'. I don't know what the agenda is in the moment, but I'm sure you'll find out more than me."
