Hadn't looked into much news about this over the past few months but heard some people talking about it on the lift. A dude was saying it had been cancelled cause Jim Carrey was not pleased with the enthusiasm from the crew over the project:
Some news articles around the summer confirmed that. However, it appears to be back on and here is a recent article:
In a Reddit AMA session held Wednesday, Peter Farrelly gave fans an update on the sequel to "Dumb & Dumber," tentatively entitled "Dumb & Dumber To." The writer/director revealed that he would love to cast to Emma Stone and Channing Tatum in the follow-up to the cult comedy.
After confirming that the original film's stars Jim Carrey and Jeff Daniels have signed onto the film, Farrelly said that he "love that guy Channing Tatum," and added that "there's an excellent role for a young dumb girl. Emma Stone would knock it out of the park."
Farrelly recently cast Stone in the new comedy "Movie 43," promotion for which he participated in the AMA. Unlike most of his movies, such as "Dumb & Dumber" and "There's Something About Mary," Farrelly did not collaborate with his brother Bobby for "Movie 43."
Earlier this month, Farrelly told Coming Soon that the script for "Dumb & Dumber 2" is finished, and the production is using non-studio financing. He told Reddit that they "hope to have an announcement soon" about further details.
Even though Farrelly would like to cast Stone in "Dumb & Dumber 2," the actress may not be so eager to take the role after Carrey caused a stir with a 2010 YouTube video professing his obsession with the then 22-year-old actress.
