Ana Gasteyer, the comic actress whose Martha Stewart impersonation kept "Saturday Night Live" viewers laughing, will join the Manhattan Theatre Club company of Kimberly Akimbo, a spokesman for the not for-profit confirmed Aug 21.

Charlotte Jones' London play, Humble Boy, has been added to the 2002-03 season, it was also announced.

Gasteyer left "SNL" in the spring to pursue other projects, and appeared in Broadway's The Rocky Horror Show. In the David Lindsay-Abaire play, she'll play the scam-artist aunt of the title character, a New Jersey teen who has a rare condition that causes her body to age at an increased rate. The middle-aged comic actress Marylouise Burke plays Kimberly, who must "reevaluate her life while contending with a hypochondriac mother, a rarely sober father, a scam-artist aunt, her own mortality and, most terrifying of all, the possibility of first love."

Performances begin Jan. 4, 2003 on MTC's Stage I. Opening night is Feb. 4, 2003. David Petrarca directs.

Lindsay-Abaire (Fuddy Meers, Wonder of the World) won the 2002 L.A. Drama Critics Award for Best Playwright for Kimberly Akimbo, seen at South Coast Rep (with Burke). It was also announced Aug. 21 that MTC would stage the American premiere of Charlotte Jones' Humble Boy, beginning April 22, 2003, on Stage I. Opening night is May 15, 2003.

The play, inspired by Hamlet, was the winner of the 2001 Critics Circle Best Play Award and a hit on the London stage. In it, Felix Humble, a Cambridge astro-physicist returns home to his bee-keeping father's funeral, only to discover his difficult and domineering mother in the arms of another man. As he struggles to find his balance in the midst of familial chaos, "what emerges is a touching, funny and entertaining dysfunctional family portrait," according to the announcement.

Humble Boy was originally produced by the Royal National Theatre. No cast has been announced.
