Bruce Willis at Vanity Fair's premiere of Oceans 13. Chicago, Illinois - 06.07.07

The 52-year-old is so pleased with Live Free Or Die Hard - which is being released internationally as Die Hard 4.0 - he wants to make another movie, but only if director Len Wiseman is on board.

He says, "Fox is already talking about another one. I told them I'd only do it if Len is involved."
