In mid-interview for a new movie last week, actress Salma Hayek suddenly shrieked and scrambled out of her seat, over the shoulders of co-star Maya Rudolph sitting next to her. Clutching frantically at Rudolph and another co-star, Maria Bello, she uttered a blood-curdling scream, "Somebody do something!" Bello, also clearly unnerved at the sight of something off-camera, comforted Hayek as she teetered on the arm of a director's chair in 4-inch heels. "It's OK," Bello repeated, "We got you. Don't worry."
