RDJ and Tom Cruise to Have Musical Showdown?

Hollywood action heroes Robert Downey Jr. and Tom Cruise won’t be fighting it out at the box office anytime soon, but if all goes to plan, they might have a sing-off. The two leading men recently became involved with separate films that would possibly see them singing on-screen in 2011.

Downey has just signed on to star in and produce (with his wife Susan) an untitled musical comedy about two Broadway songwriters who take a job at a theatre camp after their latest production flops. The Pulitzer and Tony-award winning team behind the rock opera Next to Normal are onboard to craft the music itself.

RDJ released his first album in 2004 called The Futurist to near universal “meh,” but he’d already sung on several movie soundtracks (Chaplin, Two Girls and a Guy, The Singing Detective) and Ally McBeal.

As for Mr. Cruise, he’s deep in talks with director Adam Shankman to headline the movie adaptation of Rock of Ages, which features ’80s hair metal on the Sunset Strip. “It’s all looking really good,” he told E!.

But will he sing? “Of course, he will. If he’s in it, he has to,” Shankman revealed.
