Lily isn't the only Costner that can act. Kevin's other daughter, Annie, acted alongside her sister in "The Postman" and "The Babysitters Club." Then in 2010, she appeared in a short film called "Lazy Teenage Superheroes." In recent years, Annie has started to work behind the scenes. She helped produce the 2015 film "Racing Extinction," a follow-up to the Oscar-winning documentary "The Cove." —XFINITY Entertainment Staff (Photo: Kevin Winter/Getty)
