Sylvester Stallone is trying to persuade his pal Bruce Willis to play a supervillain in "The Expendables" sequel.

Willis had a small cameo role in the summer blockbuster and now Stallone wants him to lead the cast in an all-action follow-up.

Despite initially claiming a sequel would be too expensive, Stallone appears to have been fired up by the film's success - and he's now considering a second installment.

He says, "I am thinking what would be the most dangerous places in the world to set the sequel? I had dinner with Bruce Willis... I want him in Expendables II as a supervillain. What do you think?"
