Samuel L Jackson (the L is for Leroy) exudes relaxed affability as he chats about golf and his career, but on the set he has a reputation for a commitment to his craft which can be unsettling and intimidating. Those who have worked with him say he comes to work fully prepared, having memorised not only his own lines but those of his fellow actors, and he insists on total professionalism from the cast and crew. The word in Hollywood is that he does not suffer fools gladly and wants things done his way, or not at all.
