Zac Efron And Robert De Niro ‘Party Till They’re Pregnant’ In New ‘Dirty Grandpa’ Trailer

Also, Zac gets shirtless and De Niro straddles Aubrey Plaza. Yep.

There’s a scene in the new trailer for “Dirty Grandpa” where Robert De Niro tells Zac Efron, “The greatest gift a grandson can give his grandfather is a hot college girl who wants to have unprotected sex with him before he dies.”

And that, ladies and gents, just about sums up the two minutes of debauchery that we see in this wet and wild first look at the comedy. Efron and his mighty six-pack star as an uptight groom-to-be who gets coerced into driving his lewd Grandpa Dick (De Niro) to Boca Raton, FL (in a pink Mini Cooper, no less).

But along the way, there’s Spring Break to be had! And crack to accidentally smoke! And shirtless contests to win! We see all that and more, including tons of boozed-up antics soundtracked by Macklemore, and a somewhat cringe-worthy sex scene involving De Niro and Aubrey Plaza. Yes, really.

Efron also shared the movie’s cheeky, “The Graduate”-spoofing poster on Instagram, writing, “My newest flick #DirtyGrandpa is droppin hard like a dozen eggs at the grocery store and its about to make a splash.”

Julianne Hough, Dermot Mulroney and Zoey Deutch also star in the raunchy comedy, which hits theaters on Jan. 22, 2016. Until then, here’s a GIF of Efron’s abs to tide you over.
