Sylvester Stallone has roped in another Hollywood hardman to star in new action blockbuster The Expendables - Bruce Willis has confirmed he is on-board.

Stallone has lined up some of Tinseltown's toughest stars to appear in the movie which focuses on mercenaries overthrowing a South American dictator - including Jet Li, Mickey Rourke, Jason Statham and Eric Roberts.

The Rambo actor has even enticed action hero-turned-California governor Arnold Schwarzenegger to return to the big screen in a cameo role.

And now, Willis, who has long been rumored to be appearing in the film, has confirmed he plans to shoot some high-octane scenes - insisting he's just waiting for Stallone to call him to the set.

He tells MTV.Com, "Not yet (filmed his scenes), I haven't united with them. I'm waiting for a call from Sly about when we're going to try and make that happen.

"I don't know anything about (my character) yet, haven't seen any pages yet. But I'm excited about it."

The last time the Willis teamed up with Stallone and Schwarzenegger was when the trio helped launch the Planet Hollywood restaurant chain in 1991.
