Don't expect George Clooney or David O. Russell to come out and claim their Three Kings throw-down was anything resembling love. Though the film is now regarded as some of actor's and director's best work, Clooney maintains that Three Kings was "the worst experience of [his] life."
The pair's on-set scuffle has been well documented over the years, but just to recap: the problem started because Clooney wasn't happy with how Russell treated Three Kings' cast and crew throughout production. Things got messy when Clooney witnessed Russell demonstrating how hard he wanted an extra thrown to the ground in a pivotal scene. Clooney stepped in to defend the extra, and well, tempers flared. Choice words were exchanged with Clooney reportedly telling Russell, "I told you, motherf***er, if you're going to pick on somebody, pick on me," and Russell responding, "Why don't you just f***ing remember your lines for once?" The pair then went at each other physically, having to be separated by crew members.
Though they calmed down and finished the film, the drama didn't subside. Five years after the encounter, Clooney told an interviewer, "If he comes near me, I'll sock him in the f****ing mouth." Russell responded in kind by stating, "If I ran into him, I'd say, 'Shut the f*** up, you lying-ass b****." Just FYI, that comment came as Russell was promoting I Heart Huckabees, the film that spawned his infamous on-set blow up with Lily Tomlin, so make of that what you will.
