Television stars James Roday ("Psych"), Michael Weston ("House, M.D.") and Amanda Detmer ("Private Practice") will headline the world premiere of Gabe McKinley's Extinction in Los Angeles.

Wayne Kasserman directs the Red Dog Squadron production that also features Stefanie E. Frame. Performances run Nov. 21-Dec. 13 at Hollywood's Elephant Space.

The dark comedy centers on "College buddies Max (Weston) and Finn (Roday) [who] meet in Atlantic City, where they traditionally spend their vacations in the fast lane, religiously drinking, drugging and chasing women," according to an announcement. "But this time something is different, and thwarted expectations precipitate a dangerous showdown between the two friends."

Roday, who is co-artistic director of Red Dog Squadron, currently stars on USA's "Psych." The actor, who got his start on the New York stage (The Three Sisters, Sexual Perversity in Chicago), has also appeared in the films "Don't Come Knocking," "Beerfest" and "The Dukes of Hazzard."

Weston has appeared on stage in The Waverly Gallery (Pasadena Playhouse), Snakebit (Off-Broadway) and Dead End (Williamstown Theater Festival) among others. Film/TV credits include "State of Play," "Garden State," "Coyote Ugly," "Six Feet Under," "ER" and "Scrubs."
