Jakey G will kick your ass!
Jake Gyllenhaal said that during filming of Jarhead (which I won't be seeing since I don't like war movies, except Cabaret) he got so out of hand after chipping his tooth during filming that he gave one of his co-stars a serious beat down!
He said: "For some reason. I just got so angry that I had chipped my tooth ... and just started hitting him and we didn't talk for a month after that."
Did Kiki Dunst co-star in that movie with him? Well, at least now his busted teeth will match hers!
