The 39-year-old Lost star hung out with Sean Astin while filming the comedy about a successful author who must face one of his high school crushes when he travels back home to deliver a commencement address.

Sean, (The Lord of the Rings), stars as a camp character known as Big Girl in the movie.

Hilary Duff has also been on the set of Stay Cool, filming her scenes in Santa Clara, Calif., last week.
