#15: CHARLIZE THERON AND PENELOPE CRUZ IN HEAD IN THE CLOUDS (2004)
Charlize Theron sure knows how to leave a mark. In Head in the Clouds, a 1930s-set European romance, the South African blondie engages in a passionate kiss with a just-as-ready Cruz, a first base trip that ends with Theron biting Cruz’s lip. Freaky, huh? Not to mention, very memorable—in 2006, Cruz was quoted by the New York Post as saying Theron was the best kisser she’d worked with at that point in her career. We’ll take her word for it...and resist that Jergens bottle eyeing us up from the bathroom.
