The upcoming Dumb & Dumber sequel, called Dumb and Dumber To, just added another cast member. Comedian Rob Riggle is joining returning stars Jim Carrey and Jeff Daniels, returning directors The Farrelly Brothers, and new cast member Kathleen Turner in the film, THR reports. Riggle scored one of the last major parts in Dumb and Dumber To, playing a set of twins: a repairman named Travis and his crazy brother, Captain Lippencott. The sequel’s plot involves Harry and Lloyd taking a road trip to donate a kidney to Harry’s long-lost daughter. The movie is shooting in Atlanta right now and is expected to be released sometime next year.
