British actor Robert Pattinson said at the Cannes film festival there will be a fourth installment of the "Twilight" film franchise and he will star in it.

Pattinson played the male lead in last year's supernatural romance "Twilight" and is now working on "New Moon" and "Eclipse" -- the second and third movies in the vampire series. The movies are based on Stephenie Meyer's popular young-adult novels.

Patinson, 23, told The Hollywood Reporter he has signed on to appear in a fourth flick based on Meyer's book "Breaking Dawn," but added he doesn't known when Summit Entertainment will begin shooting it.
