Dirty Grandpa Red Band Trailer: Robert De Niro Gone Wild

Every generation has its "party movies". From Animal House to American Pie to even the found-footage movie Project X, comedies revolving around partying protagonists are about as American as baseball. These films consistently reaffirm the fun of youth and the adventure that goes along with it.

However, just because one gets old does not mean they forget how to have a good time. If the new trailer for Dirty Grandpa is anything to go by, older generations can still show us a thing or two about having a good time.

Lionsgate has now officially dropped the red band for Dirty Grandpa. The film revolves around recent widower Dick Kelly -- played by Robert DeNiro (Silver Linings Playbook) as he and his grandson Jason -- played by Zac Efron (Neighbors) venture down to Daytona Beach for spring break. Along the way they get into absurd amounts of trouble, replete with lots of binge-drinking, crack-smoking, and sex with college co-eds. The film also stars Julianne Hough, Aubrey Plaza, and Zoey Deutch.

While not the first trailer for Dirty Grandpa to hit the web, this is the one that should get audiences excited. A few weeks ago Buzzfeed premiered the green band trailer for the film, which by and large followed similar story beats but lacked the vulgar punch of this version. It's the sort of film we have come to expect from Efron in particular, who has carved out a niche for himself as a strong performer in raunchy comedies - a trend which began with 2014's Neighbors and will continue at least through the upcoming Baywatch reboot.

At its core, the film appears to have all the qualities of a raunchy comedy, but there seems to be more to it than that. Between the shots of partying and the exchanges of dialogue that we definitely cannot quote directly, there are moments where DeNiro's character shows some genuine -- albeit brief -- moments of pathos.

It's abundantly clear even at this early stage in the film's marketing campaign that Dick is harboring some demons, which compels him to take Jason to Daytona. It's not dissimilar to Bill Murray's recent film St. Vincent, which similarly centered upon a hard drinking, rough around the edges protagonist harboring his own personal demons.

Dirty Grandpa opens in U.S. theaters on January 22nd, 2016.
