Robert De Niro, Aubrey Plaza Have Sex in ‘Dirty Grandpa’ Trailer While Zac Efron Smokes Crack

Robert De Niro went through a weird career phase of just playing sad old guys, but in the new trailer for Dirty Grandpa, the legendary actor appears to be anything but sad. In fact, he's actually pretty feisty (and incredibly raunchy) given that sex scene he appears to have with former Parks and Recreation star Aubrey Plaza.

Starring De Niro alongside Zac Efron, Dirty Grandpa follows the two on a grandson-grandfather spring break-like road trip just after Efron's grandmother, and De Niro's wife, has passed away. Shockingly enough, the grandfather he once knew appears to be no more, as all the Meet the Parents star wants to do is find some young college girls to, well, "get out there" with.

And in this film, it's Plaza.

Naturally, Efron's character is hesitant – and downright against it – in the beginning, as his character is about to wed Julianne Hough, but as these movies tend to do, he succumbs and all hell breaks loose.

That, and he also smokes some crack with Jason Mantzoukas.

Wait, what?! Yep, really...

So, is this Robert De Niro like we've never seen him before? Anyone psyched to see that hot(?) sex scene between Aubrey Plaza and De Niro?

Let us know your thoughts below, folks.

There was some speculation as to when the film would be released. Most people have said that it'll be sometime in 2016, however, per Efron's Instagram account, it looks like the film will hit theaters early on in the year. 

Dirty Grandpa will be released this coming Jan. 22,
