Were you born to be a porn star? Me neither. But that’s the premise of “Born to Be a Star.” Written and produced by Adam Sandler, the comedy focuses on a Middle American nerd, played by Nick Swardson, who discovers that his parents were porn stars. Christina Ricci plays the born-into-porn dude’s girlfriend and Stephen Dorff will put in an appearance as a legendary woodsman known as “Dick Shadow.” Of course, the story idea isn’t so out there so as not to be believed. Actress Thora Birch of “American Beauty” fame? Both her parents were porn stars. Her mother, Carol Connors, appeared in “Deep Throat,” on the set of which she met Thora’s father, Jack Birch. Also? Her mother, uh, performed with John Holmes in “The Erotic Adventures of Candy.” Now that’s got to be embarrassing. [Variety] Want to find out more about Hollywood stars’ secret porn pasts?
