UPDATE: READ ON FOR THE COVER ART! Spurred by the success of its direct-to-video horror “Rest Stop,” Warner Home Video is set to release a second film in its edgy “Raw Feed” series. Sublime — about a man admitted to a hospital for a routine procedure, only to discover that he’s landed in a ward of horror where patients come not to get better but to die — will be released on March 13, according to Yahoo. The creative team behind “Sublime” consists primarily of young television talent. The cast includes Tom Cavanagh (“Ed”) and Kathleen “Bird” York (“The O.C.”). It will screen at the Cinequest Film Festival in San Jose, Calif., shortly before its DVD premiere. “Raw Feed” was launched in March under the home entertainment division’s theatrical catalog group. The line consists of adult-themed genre films, mostly sci-fi and horror, with budgets of up to $5 million.
