The first trailer for Dumb and Dumber To has been unveiled on Jimmy Fallon's Tonight Show, seeing Jim Carrey and Jeff Daniels leap back into the roles of perpetual idiots Lloyd Christmas and Harry Dunne.
The trailer sees the characters 20 years on, with Harry tracking down Lloyd at a mental hospital, where he has been pretending to be crazy for decades simply for the gag.
The pair later learn that Harry has a daughter (whom Lloyd is harbouring a crush on) and set about tracking her down.
Despite the actors having gone on to much more serious roles (Daniels recently headed up the cast of The Newsroom, Carrey's films include Eternal Sunshine of the Spotless Mind) they are back on gleefully silly form here, shouting and screaming and gurning and generally throwing themselves around the set.
The trailer sees arson at a motel, the pair take a pit stop in the middle of a highway and the return of their infamous dog van.
The Farrelly brothers are back to direct the sequel, which will also see a cameo from Jennifer Lawrence.
Carrey and Daniels appeared on Fallon as the trailer premiered, also doing a sketch with the host called 'Real People, Fake Arms'.
Dumb and Dumber To has a US release date of 14 November in the US and opens in UK cinemas a month later on 19 December.Reuse content
