They join Jim Carrey and Jeff Daniels in the sequel set for release next year (2014)

Kathleen Turner and Brady Bluhm have signed up to appear in the new Dumb And Dumber movie.

They join Jim Carrey and Jeff Daniels in the eagerly-anticipated sequel, which directors Bobby and Peter Farrelly are due to start shooting this month (September).

The Farrelly Brothers used Twitter to confirm both castings and reveal that Turner will play a character called Fraida Feltcher who was mentioned in the original Dumb And Dumber film as a “babe who worked for the tractor company” – and who has romantic history with both Daniels’ Harry and Carrey’s Lloyd. Meanwhile, Bluhm will reprise his role as Billy in 4C, the blind boy to whom Harry and Lloyd sold their headless bird, Petey.

The Farrelly Brothers have also announced recently that Empire Of The Sun will be scoring the sequel, whose official title is Dumb And Dumber To. It’s set for release in 2014 to mark the 20th anniversary of the original film.

Written and directed by Peter and Bobby Farrelly, 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 it did not feature the original stars or any involvement from the Farrelly Brothers.
