jackass presents: Bad Grandpa

Those Jackass jokers unleash more "don't try this at home" stuff as front man Johnny Knoxville piles on the latex as his 86-year-old screen alter ego, Irving Zisman. Set within a loose framework that sees Zisman taking his eight-year-old grandson on a cross-country road trip, the film soon reveals itself to be yet another excuse for the usual combination of stunts and staged situations, with Knoxville and kid suffering or inflicting assorted indignities on apparently unsuspecting members of the public. Prankster scenarios include Zisman being forcefully ejected from a kiddy car-ride, disrupting an already creepy beauty pageant and generally taking centre stage in japes too mucky to mention here. Suffice to say, many feature either bodily functions or penile prosthetics. It's patchy and marginally less gross than previous Jackass films. But you will laugh. Guaranteed.
