Redbelt is both written and directed by David Mamet, of House of Games, State and Main, Heist, and most recently "The Unit" on TV. The film is an original script written by Mamet, who also wrote the screenplays for The Untouchables, Glengarry Glen Ross, Wag the Dog, Ronin, and Hannibal. Redbelt arrives in limited theaters starting on April 25th.

That alone makes me want to see it.
