Lloyd and Harry are returning to the big screen for the first time in almost 20 years.
Jim Carrey andhave reunited with Bobby and Peter Farrelly for the upcoming (that's not a typo), the sequel to the 1994 hit comedy.
The two actors reprise their roles as the dimwitted duo who embark on yet another road trip, only this they're time in search of a long-lost child to serve as a kidney donor.
The cast and crew began filming on the sequel Tuesday in Atlanta, and the first on-set photos have already arrived.
Both Carrey and Daniels have taken to social media to tease how they'll look in costume.
In one of the photos, the pair can be seen reading an upside-down copy of Carrey's recently-published children's book, "How Roland Rolls."
On a budget of $17 million, the first "Dumb and Dumber" film was a box office smash, grossing over $247 million worldwide.
A 2003 sequel, "Dumb and Dumberer: When Harry Met Lloyd," (which didn't have any involvement from Carrey, Daniels or the Farrellys) became a critical and commercial disaster.
"Dumb and Dumber To" arrives in theaters in 2014.
