Johnny Knoxville and his merry band of morons take their scatological sideshow from MTV to the big screen. Freed from the constraints of the small box, they get to expand their repertoire of stupid stunts and gross-out gags so they can shit in their pants and show the result. They even launch bottle rockets from their sphincters and get blow jobs from whale sharks. More interesting, however, is the tattoo session in a Hummer, with rocker Henry Rollins driving it at breakneck speeds and off the road. Then there's the female kickboxing champ who beats the bejeezus out of the boys, and an enthralling skateboarding session with ace Tony Hawk.

Comical, yes, but not for the faint of heart -- the cameraman tosses his lunch on several occasions. The limit to Jackass is that there's zero plot and the antics get played out midway. The real show at the screening I attended, however, was the trio of suits in front of me who waxed on idolatrously about the nutty nimrods. I smelled reefer madness, but no one shared with me -- perhaps that's why I didn't get the full ass effect. (80 minutes) At the Apple Valley, Campus, Entertainment, Flagship, Holiday, Providence Place Mall 16, Showcase, and Tri-Boro cinemas.
