Stephen Lang landed his role in Avatar after punching a man in the head while auditioning for director James Cameron.
The actor was in the running for the role of Colonel Miles Quaritch and managed to secure his place in the biggest-grossing film of all time after attacking an actor standing next to him during his casting.
Lang tells the BBC, "He (Cameron) remembered that I had auditioned for him years before for Aliens - I didn't get the part but something clicked for him and we started speaking and had a meeting.
"I went out to see him in Malibu and it was wonderful because it was never put in terms of being an audition - it was sort of a work session.
"Apparently at some point, I grabbed the young actor who was sort of off camera and I smacked him in the head.
"He was a real buff guy! Jim said when I clocked him I got the part right there. So that's my advice to young actors!"
