Stickmen

Stickmen is a 2001 New Zealand film directed by Hamish Rothwell and starring Robbie Magasiva. The screenplay concerns Thomas, Jack and Wayne, who are the best of mates. Each of them lives their life the way they play pool. Thomas is either absolutely brilliant or absolutely crap. Jack is always slick, cool and forever setting up the next shot. Wayne bumbles his way through life happy to be the guy that always says the wrong thing at the wrong time. During the high-stakes underground eight-ball tournament run by Daddy, a Greek crime lord, they encounter a weird and wonderful collection of people on their way to compete for the big prize.
