The intense gay sex scenes in James Franco's new film, King Cobra, are apparently so hot that they had Alicia Silverstone turned on.

The Clueless actress appears in the film as the mother of porn star Sean Lockhart (a.k.a. Brent Corrigan), played by Garrett Clayton.

The movie recounts the real life murder of adult-movie producer Bryan Kocis (Christian Slater) at the hands of porn actors Harlow Cuadra (Keegan Allen) and Joseph Kerekes (James Franco), who wanted to make Lockhart their new star.

"I thought it was really sexy," said Silverstone of her reaction to King Cobra's aggressive sex scenes. "There's a particular scene where Christian Slater is watching his young budding star audition for him. And watching him watch him is so erotic."

Below, we talk to Silverstone and her King Cobra co-stars.
