Dirty Grandpa review – avoid at all costs

Robert De Niro and Zac Efron earn a place in cinema’s hall of infamy with an atrocious bad-taste comedy

Ever wanted to watch Robert De Niro jerking off over porn tapes and repeatedly jamming his thumb up Zac Efron’s ass? Ever felt the need to see Efron strap a stuffed toy on to his penis and comically simulate oral sex with a minor? If the answer to either of these questions is no, then steer away from Dirty Grandpa, just as you would sidestep a dog turd on the pavement. The plot is simple – De Niro’s recently widowed OAP gets his grandson to drive him to Florida so that he can “fuck fuck fuck fuck fuck” a much younger woman (Aubrey Plaza) by pretending to be a college professor.

En route, Zac’s uptight lawyer will smoke crack, get threatened with anal rape, and wear clothes splattered with crime victims’ blood and semen. Long-time Sacha Baron Cohen collaborator Dan Mazer directs, leaving us longing for the cock-in-a-slot-machine subtlety of Jackass Presents: Bad Grandpa from which this steals its star-studded riffs. Somewhere, in the very bowels of hell, Dirty Grandpa is playing on an eternal double bill with Movie 43, awaiting the arrival of all involved.
