Zac Efron Goes to Bed with Robert De Niro in New 'Dirty Grandpa' Photos

Zac Efron lays in bed with co-star Robert De Niro in this new image from their upcoming film Dirty Grandpa, out in theaters next month.

A new teaser poster for the movie was released along with two photos showing the leading men.

Here is the full synopsis: Jason Kelly (Efron) is one week away from marrying his boss’s uber-controlling daughter, putting him on the fast track for a partnership at the law firm. However, when the straight-laced Jason is tricked into driving his foul-mouthed grandfather, Dick (De Niro), to Daytona for spring break, his pending nuptials are suddenly in jeopardy. Between riotous frat parties, bar fights, and an epic night of karaoke, Dick is on a quest to live his life to the fullest and bring Jason along for the ride. Ultimately, on the wildest journey of their lives, “dirty” Grandpa and his uptight grandson discover they can learn from one another and form the bond they never had.

Aubrey Plaza, Zoey Deutch, and Julianne Hough all star in the movie, hitting theaters on January 22.
