After Peter Farrelly, one half of the Farrelly Brothers, confirmed plans for a follow-up to "Dumb and Dumber" in April of this year, it looked like fans of the original Jim Carrey and Jeff Daniels comedy would finally get what they wanted: a true sequel.

Plans to start filming with Carrey and Daniels this year now seem to be derailed, however. "Entertainment Tonight" is reporting that Carrey has left the project, which was supposedly titled "Dumb and Dumber To," due to a dispute with the studios, New Line and Warner Bros.

The "ET" website offered the following insight into why Carrey left the film: "According to sources, Carrey grew increasingly frustrated by New Line and Warner Brothers, who he felt showed a lack of enthusiasm regarding the project."

Carrey's representatives passed along this official statement from the actor. "I would have thought 'Dumb and Dumber To' was a no-brainer," he said. "After all, it's implied in the title."

If the conflict with Carrey is not resolved, his exit would surely jeopardize any hope for an official sequel to the 1994 comedy. A prequel, "Dumb and Dumberer: When Harry Met Lloyd," released in 2003 without Carrey or Daniels, was never sanctioned by the Farrelly Brothers and bombed at the box office, debuting in the sixth spot in its opening weekend.

While promoting "The Three Stooges," Farrelly had confirmed that both leads would reprise their roles and that shooting would hopefully begin in September.
