Doddery, deadpan Irving Zisman (Knoxville) and Billy (Nicoll), his grandson-cum-accomplice, travel across the States unleashing a blizzard of pranks on an unsuspecting public.
With Steve-O AWOL and Ryan Dunn having passed away, this latest Jackass marks a change in format: the pranks are framed by a road-trip plot. Cloaked under grandpa make-up, Johnny Knoxville’s randy pensioner gets lumbered with his deadpan grandson (Jackson Nicoll), due to be offloaded on his loathsome dad. As they drive across state, the duo punk the public in a series of antisocial sketches. For all its genital-chewing soda machines and diner-redecorating dynamite sphincters, the pranks are milder than usual but no less invigorating. Inevitably sketchy, but when it hits, it’s hilarious — and Knoxville’s fantastic.
True to the Jackass formula, some gags come off better than others, but there's some doozies in its midst.
