Dumb And Dumber producers Brad Krevoy and Steve Stabler got personal in a countersuit filed today against Red Granite Pictures and its principals Joey McFarland and Riza Aziz. The pair are suing for compensation they claim they’re owed on the upcoming sequel Dumb And Dumber To, which is being prepped without their involvement by Red Granite who stepped in to back the project after WB fell out. Accusing McFarland and Aziz of “unlawful and unethical conduct,” Krevoy and Stabler’s suit asserts that they were wrongfully squeezed out of the sequel by the Red Granite camp and demand $400K they say they’re entitled to based on their initial contract with New Line.

But it gets juicier. “McFarland’s and [Aziz’s] misconduct and hubris will cause Red Granite to crash and burn,” continues the suit, questioning whether other talent on the project will want to work with the company. “Further, McFarland and [Aziz] lack the experience necessary to successfully produce motion pictures themselves. Although Red Granite apparently has family money from [Aziz], Red Granite will not succeed with money alone because McFarland and [Aziz]’s experience producing motion pictures during their short tenure in the industry consists of cavorting at nightclubs with Paris Hilton and making dinner reservations at posh nightclubs in New York and Los Angeles.”

Last week financiers Red Granite initiated the Dumb and Dumber beef with a filing seeking the court’s declaration that it owes Krevoy and Stabler no producers fees or credits on the sequel. Krevoy and Stabler outline their complaints against Red Granite in decidedly less aggressive terms in a statement obtained by Deadline:

Brad Krevoy and Steve Stabler were intimately involved in every aspect of the development and production of ‘Dumb and Dumber,’ were on the set every day and gave their hearts and souls to that movie. They were the ones who made it happen with Peter and Bobby Farrelly and producer Charlie Wessler on a movie that was their directorial debut. As stated in the complaint that our clients filed today, it is outrageous that Riza Aziz and Joey McFarland would try to exclude our clients when they have a written contract that governs their participation and compensation in all future sequels and remakes.

This is a pattern of conduct that McFarland and Aziz have repeated, having tried to do the exact same thing to Alexandra Milchan on The Wolf of Wall Street. They think they can arbitrarily wave a wand and make facts go away, but that is not the case with our clients.
