It doesn't take a genius to see that Bruce Willis has never exactly come across as a barrel of laughs. He is known for playing intense, moody parts, and even his humorous cameo on Friends saw him play an intimidating character. It appears that the Die Hard star doesn't seem to have to venture too far away from his normal self, however, and he is not great fun to be around on set. Director Kevin Smith, who worked with Willis on the hugely forgettable Cop Out, described the 59-year-old as "soul crushing to work with", while Sylvester Stallone called him "greedy" and "lazy" on Twitter, after a falling out about The Expendables 3. That was supposedly to do with Willis demanding $4m for four days work on the film, which Stallone and his co-stars did not like one bit. Willis subsequently pulled out of filming, and Stallone tweeted his delight that Harrison Ford had replaced him instead. Willis continues to attract huge wages for his films, and remains a pretty big box office draw, but it's clear to see that there are many who have worked with him who would happily not speak to him again.
