‘Dirty Grandpa’ Trailer: Zac Efron And Robert De Niro Party Until You’re Pregnant

Johnny Knoxville already brought us the wild antics ofBad Grandpawith his trustyJackasscrew, preying on the clueless public with hidden cameras and prosthetic genitals. NowRobert De Nirois trying to get in the geriatric tomfoolery game withDirty Grandpa.

The new raunchy comedy from directorDan Mazer(I Give It a Year) sees the iconic star ofTaxi Driver, Raging BullandGoodfellasas the grandfather ofZac Efron, the uptight grandson who is tricked into driving through Daytona Beach during the insanity of spring break. Now the firstDirty Grandpatrailer has arrived, delivering pretty much exactly the kind of debauchery you’d expect.

Here’s the trailer forDirty Grandpa, originally fromBuzzFeed:

During this detour on the way back home to his impatient and worried fiancée (Julianne HoughofRock of Ages), Jason (Efron) gets some not-so-grandfatherly, but potentially helpful advice from Dick (De Niro) about marrying a woman who may not be right for him at all. So of course he needs to sow his oats among all the shenanigans in Florida.

There’s all the spring break partying you’ve come to expect from movies like this, including girls dancing in bikinis, plenty of drinking and drugs, and of course, Zac Efron shirtless. Even De Niro gets his shirt off during this wild road trip, and Plaza is being much more saucy than we’ve ever seen her before, though it’s more than a little weird seeing her get frisky with the veteran actor.

It’s basicallyPlanes, Trains & AutomobilesmeetsThe Hangover, with De Niro as a foul-mouthed, horny and inappropriate grandpa and Efron doing the opposite of his character inNeighborsby playing the straight man who ultimately succumbs to the party. Unfortunately, it doesn’t look nearly as good as any of those aforementioned comedies, even if they are driving around in a car that De Niro calls a “giant labia.”

Despite the craziness this trailer shows off, it doesn’t get nearly as raunchy as the movie likely will be. There are plenty of cuts away from profanity, and CG underwear has been added to Efron while he does crack withJason Mantzoukas(Sleeping with Other People), and Aubrey Plaza (or at least a body double of theParks and Recreationstar) while she straddles De Niro in a hotel room.

Dermot Mulroney, Zoey Deutch, Adam PallyandHenry Zebrowskialso co-star in the comedy which arrives early next year onJanuary 22nd, 2016.
