Few things are as scary as the thought of Jackass in 3D

Par and MTV Films are even further along with "Jackass 3," with filming scheduled to begin Jan. 25. The studio has carved out a spot on its 2010 slate for the latest "Jackass," which will star Johnny Knoxville. The low-brow franchise has been something of a cash cow for the studio with the first two films -- which together cost $16.5 million -- raking in a combined $164.1 million worldwide.

Though Par confirmed the new "Jackass" will be shot in 3D, Dickhouse Prods. declined comment about the technology the film will employ. Insiders say Dickhouse's Jeff Tremaine, who will direct "Jackass 3," is conducting camera tests this week to ensure that the footage will look good.
