David Mamet

Actor and Director William H. Macy. He's been associated with playwright and film director David Mamet for over 15 years. He appeared in the original productions of Mamet's American Buffalo and The Water Engine. He's appeared in Mamet's films, "House of Games," and "Things Change." Now he's directing the theatrical debut of Mamet's play, "Squirrels," at the Philadelphia festival of New Plays. One of Macy'S earliest acting roles was in the workshop production of "Squirrels" in the 1970's in Chicago.

Jonathan Katz stars as standup comedian Jackie Shore in the new movie Things Change, which was written by his friend David Mamet. Katz played a con man in the earlier Mamet movie House of Games, which Katz says was loosely based on their experience as small-time ping pong hustlers.

Stage and screen actor Joe Mantegna. He can be seen now in "House of Games," the first film effort by Pulitzer Prize-winning playwright David Mamet, with whom Mantegna has had a long association. His stage work includes the lead role in "Glengarry, Glen Ross," the Mamet play that won the 1984 Pulitzer Prize; Mantegna won a Tony Award for his performance. Mantegna revels in shady characters: gamblers, cutthroat salesman, mobsters and Hollywood hucksters.
