Kiefer Sutherland is reteaming with his 24 co-star Stephen Fry for work on a secret film project.

The British actor joined the cast of Sutherland's hit action drama for reboot series 24: Live Another Day, which has been filmed in the U.K., and Fry now reveals the pair is working together again on a short film.

Fry gave away the news in a post on his page on Friday (27Jun14), writing, "At secret place filming secret short film secretly with @RealKiefer in secret for @SproutPictures #secretsquirrel."

Sprout Pictures is the independent Film and Television production company co-owned by Fry. The firm has produced Chris O'Dowd's Tv show Moone Boy and several installments of the Sky Playhouse Presents series.
