Three new cast-members are joining the four-actor comedy, Snakebit, running since March 1 at the Century Center Off Broadway. Among the new arrivals, starting June 8: Bill Brochtrup, best known for playing the gay secretary on TV's "NYPD Blue." He's joined by Guillermo Diaz, of filmdom's "200 Cigarettes" and "Party Girl"; and Christopher Gartin, of TV's "Party of Five." Gartin also replaced Paul Rudd in the Broadway run of The Last Night of Ballyhoo. Jodie Markell, who plays the sole female character, remains with the show, which is scheduled to run (at least) through the summer.

The Naked Angels production of actor-playwright David Marshall Grant's comedy first opened Nov. 22, 1998 at the Grove Street Theatre to good reviews and quickly extended its run until Dec. 20. The show, directed by Jace Alexander, reopened at the Century Center March 1, 1999.

As an actor, Grant is known for his stage role as Joe Pitt in Broadway's Angels in America, and as a recurring character in ABC's "thirtysomething."

Snakebit concerns friends facing a crossroads in their lives and friendships. One is a self-centered actor (Gartin) allowing his career to overrun his marriage; another, Michael (Brochtrup), is a passive-aggressive gay friend still smarting over his last relationship. We also meet the neglected wife (Markell) and the new boyfriend (Diaz) of Michael's ex.

Designers are Dean Taucher (set), Elizabeth Roles (costumes), Renee Molina (lighting). Daryl Roth, Hal Luftig and Ted Snowdon are producing. The nonprofit Naked Angels was founded by a group of writers, actors and theatre artists in 1986. This is the 13th season for the company, which developed and premiered Jon Robin Baitz's The Substance of Fire and A Fair Country, Nicky Silver's Fat Men in Skirts and more.

The Century Theatre is at 111 E. 15th St. Call (212) 239-6200 for tickets.
