Notable role (as a child): Kathyrn in That Night (1993)

Fun fact: Katherine Heigl started off as a child model before she turned to acting. Another fun fact: her first on-screen role was shared with then-youngin' Eliza Dushku, the star of the film. Not so fun fact: These days, she's known for her insufferable amount of rom-coms, such as One for the Money and The Ugly Truth.
