The Repertory Theatre of St. Louis has extended its Studio Theatre production of Harold Pinter's Betrayal, the marriage drama that tells its story in reverse, revealing the climax first and then its previous episodes. The show was set to closed Nov. 15, but due to successful ticket sales and positive critical reaction, Betrayal remains in the Studio for one more week.

Previews played Oct. 28-29 for an opening Oct. 30. Betrayal features the triangle of Carolyn Swift as Emma, Chris Hietikko as Jerry and Anderson Matthews as Robert. Jerry Vogel plays the waiter/bartender roles, under Rep artistic director Steven Woolf's direction.

Designers are John Roselevich (sets), Bruce Summers (costumes) and Mary Jo Dondlinger (lighting).

The Studio Theatre at St. Louis Rep is a flexible "black box" space that seats up to 125 people. The space is downstairs from the mainstage, in the Loretto-Hilton Center in Webster Groves, MO.

Also on the 1998-99 Studio Theatre season schedule: How I Learned to Drive by Paula Vogel (Jan. 20-Feb. 7) and As Bees in Honey Drown by Douglas Carter Beane (March 24-April 11). For ($20-$29) ticket information, call (314) 968-4925.
