Jackass: Bad Grandpa Trailer Lands, Knocks Over Your Wedding Cake

Johnny Knoxville ages disgracefully

Johnny Knoxville is back, and he's aged dramatically. Taking the Jackass character of Bad Grandpa into his very own spin-off movie - that's Jackass Presents: Bad Grandpa - the master of semi-organised disaster is proving once again that he's perfectly happy to run things over in his car, or fly through a shop window on a children's ride. Strap in folks, it's going to be a bumpy night.

The story of the film is simple: Knoxville's Irving Zisman must take his eight-year-old grandson Billy (Jackson Nicoll) cross country to be with his father, but he's got a nasty habit of being a bit of a bastard, something which frequently gets him into trouble. So expect lots of falling over, explosions, swearing and real-life reactions. Also, no wedding cake. Sorry about that.

Jackass Presents: Bad Grandpa is out on October 25.
