This one has become something of a legend, even though both actors involved have denied its occurrence, but the modern myth goes like this: one day while filming Charlies Angels, Bill Murray told co-star Lucy Liu bluntly in the middle of shooting a scene: You cant act. The actresss response to this slight? To start wildly volleying punches at Murray - the two had to be physically separated, or so the story goes, and sent to their respective corners. Talk of creative differences between the two had crept up prior to this alleged fist-fighting incident; one such creative difference apparently culminated in a shouting match, wherein, as Murray puts it, the two threw hand-grenades and skyrockets at one another (hopefully figuratively). While Murray denies it, its said that the reason he refused a role in the sequel was because of Lucy Lius involvement. Whether or not this is true will remain unknown.
