The frighteningly hip Cabana Club in Hollywood provided the backdrop for the premiere of one of the more frightening films in recent memory, “The Exorcism of Emily Rose.” Stars Laura Linney, Shohreh Aghdashloo and newcomer Jennifer Carpenter were among those seeking sanctuary at the club’s bars and poolside tables after watching the creepy movie about demonic possession.

“It was a beast,” says Carpenter of her demanding title role, which required performing seizure-like contortions. “(Director Scott Derrickson) wanted to stay away from CGI and blue-screen effects, so, while it was hard, I had permission to just make stuff up on the fly. And adrenaline’s a great acting tool.”

Also mingling in the low-lying mist billowing from too many fog machines were producers Tom Rosenberg, Clint Culpepper, Beau Flynn and Gary Lucchesi.
