"Speed Racer" is roarin' onto the big screen as one of this summer's box office blockbusters, and "Extra" gets the scoop from its stars, Emile Hirsch and Christina Ricci. Hirsch -- whose participation in the action-packed racing adventure is expected to turn him into a bona-fide heartthrob -- spills about his real-life dream girl and his Hollywood mentor Sean Penn. Ricci also opens up to "Extra" about the flick, and envy for the derriere of a fellow actress!

Check out Emile and Christina as they hit the road in "Speed Racer" on May 9.
