It's curtains for Killer Joe. The long-running Off-Broadway hit, about a psychopathic family dealing with a sociopathic cop, stops doing time at the Soho Playhouse June 27. Tracy Letts' play was to close June 13, but then the producers secured the return of original cast member Scott Glenn, so the run was extended two extra weeks.

The production, which has nudity, violence, hints of incest, murder, profanity and other familial niceties, co-stars Michelle Williams ("Dawson's Creek") as a confused virgin who becomes the pawn in an increasingly ugly game.

Killer Joe made its Off-Broadway debut October 1998 with Glenn and Amanda Plummer and is the story of a dysfunctional Texas trailer park family: son Chris, who needs quick cash to pay off a drug debt; his father Ansel who's in no position to help him; his manipulating step mother; and his innocent sister Dottie. Chris' real mother has stolen the only "assets" he has, leaving him only one way out, until Killer Joe Cooper enters the scene.

Past cast members have included: Amanda Plummer ("Pulp Fiction," "So I Married an Axe Murderer"), Lori Petty ("A League of Their Own"), Fairuza Balk ("Waterboy,""The Craft"), Jan Leslie Harding (I've Got the Shakes), and Paul Dillon ("Austin Powers").

Dillon originated the title role of Killer Joe in Chicago and came into the New York production when Glenn's contract ran out. Wilson Milam helmed the piece, with Greg MacPherson on lights, George Xenos (set) and Jana Stauffer (costumes). David Brimmer served as fight choreographer. Killer Joe premiered at the Lab space of Evanston, IL's Next Theatre in 1993. Tracy Letts' play was staged in New York in 1994 by 29th Street Repertory.
