He has put himself through some of law school thanks to his effectiveness at the card tables. Later his good friend from years ago is released from prison. Mike of course is part of the reason Worm was in jail and he feels that he owes it to Worm to pick him up when he gets out.
Rounders is a fascinating and extremely well thought out film with great actors on all fronts.
The film takes us into the seedy underground of high stakes poker games in the back rooms of the big city. We are introduced to a variety of characters who are almost totally cast to perfection. Matt Damon is one of the hottest actors going right now and has that image of the boy next door that could never get in any trouble. These two are the great combination that you would expect to find as friends. They both have very distinct personalities and are as different as they are similar.
