The Dirty Grandpa movie, released on January 22, 2016, lives up to its name. It is just downright dirty. The film was released by LionsGate, written by John Phillips, and directed by Dan Mazer. It stars Zac Efron as Jason Kelly; Robert DeNiro as Dick Kelly, Jason's grandfather; Aubrey Plaza as Lenore; and Zoey Deutch as Shadia, Jason's love interest[1], according to Wikipedia.
Warning: Major spoilers ahead!
Robert De Niro takes on the role of Dick, a former Army general whose wife has recently passed away. He is a grandfather, but not a stereotypical one. The man is foul-mouthed, crude, homophobic, and racist. Early on in the movie, his grandson, Jason, walks in on him to find Dick pleasuring himself in a reclining chair while watching an X-rated movie.
