Jim Carrey and Jeff Daniels return as Lloyd Christmas and Harry Dunne

The first official trailer for the upcoming Dumb And Dumber To has been released.

The trailer was posted online over night and shows Jim Carrey and Jeff Daniels in character as Lloyd Christmas and Harry Dunne.

The original Dumb And Dumber came out in 1994 and starred Carrey and Daniels as dimwitted friends on a road trip. A prequel called Dumb And Dumberer: When Harry Met Lloyd followed in 2003 but did not feature the original stars or any involvement from the Farrelly Brothers.

Peter and Bobby Farrelly began filming their eagerly-anticipated sequel in September last year. Dumb And Dumber To will follow Harry and Lloyd as they embark on a road trip to find Harry’s long-lost daughter.

The cast also includes Kathleen Turner, The Walking Dead’s Laurie Holden and Brady Bluhm, who appeared in the original film as Billy in 4C, the blind boy to whom Harry and Lloyd sold their headless bird, Petey. Meanwhile, Hunger Games star Jennifer Lawrence has already visited the set to film a cameo appearance.

Dumb And Dumber To has no official release date yet but is expected this year (2014) to mark the 20th anniversary of the original film.
