The now infamous dog van is back, along with all the crass humour that Lloyd and Harry were known for.

Jeff Daniels and Jim Carrey both appeared on The Tonight Show with Jimmy Fallon last night to premiere the trailer of Dumb And Dumber To which is going to be hitting Irish cinema screens in December.

The new movie’s plot centres on the search for Harry’s (played by Jeff Daniels) daughter, who he finds out about later in life and discovers that she has been adopted.

The original movie is now nearly twenty years old, having first been shown in 1994.
