Rob Riggle has signed on for one of the last major roles in Universal's comedy sequel Dumb and Dumber To, which is currently shooting in Atlanta.

The actor is actually taking on a dual role, portraying Travis, a handyman, and his unstable twin brother Captain Lippencott. Jim Carrey and Jeff Daniels reprise their roles as Lloyd Christmas and Harry Dunne from 1994's Dumb and Dumber, who hit the road once again to find Harry's long-lost daughter, who is in need of a kidney transplant. We first reported on the sequel's story last August, although it wasn't known which of the duo's child it was until now.
