Johnny Knoxville did it better. A career military nutjob (Robert De Niro) observes his future granddaughter-in-law texting at his wife’s funeral and decides a Hangover-style road trip is just what his uptight grandson (Zac Efron) needs to derail the pending nuptials. The script rat-a-tats like a gatling gun misfiring one forced encounter and unifunctional character after another. (You’ll want to scream every time Jason Mantzoukas pops up to hold court as a cavalier drug peddler.) De Niro’s performance consists of giving the deep wrinkles of his shar-pei mug an extreme workout while phoning in the prosaic profanity. Not the nadir – that’s Stardust, the only one of his films I couldn’t see through to the end – but damn close. (The sight of De Niro pleasuring himself to porn left permanent retinal damage.) One huge laugh: Julianne Hough plays a character named “Goldstein.” Directed by Sacha Baron Cohen gag-writer Dan Mazer. (2016) — Scott Marks
