Sly still Bruce's buddy

Sylvester Stallone has assured fans reports of a falling-out between himself and Bruce Willis are not true.

The action man has confirmed Willis was invited to return to The Expendables franchise for the upcoming third film but the reunion "didn't work out".

Harrison Ford has instead joined the cast and will play Drummer.

"That happens in film and casting. It's nothing personal," Stallone said.

"It sounded like it got personal and I'm sorry it did sound that way. But it was actors talking and things move on. I think Bruce Willis is a great guy and he does fantastically entertaining films."

Stallone has revealed he and Ford became great friends when they were struggling actors looking for a break back in the late 1970s.
