Since October of last year, The Farrelly Brothers have planned on making a sequel to Dumb and Dumber their next film. However, this past June, Jim Carrey dropped out of the project with the actor saying he was “frustrated” by the lack of enthusiasm on the part of Warner Bros (details later surfaced that he was also frustrated by the payday he would have received). Despite Carrey’s lack of participation, the sequel still appears to be going forward with the Farrellys tweeting [via Vulture], “You also might be interested to know that we are almost done with the Dumb and Dumber To (sic) script. I think you’re going to like it.”
As for the plot details, the Farrellys said last month that the movie will revolve around either Harry or Lloyd possibly having sired a child, and then needing to find the child so they can get a kidney replacement.
