Robert De Niro and Zac Efron star in NSFW ‘Dirty Grandpa’ trailer – watch

New teaser for their raunchy comedy film is packed with adult language and sexual innuendo

A second trailer for Dirty Grandpa starring Robert De Niro and Zac Efron has been released.

The new teaser for the upcoming raunchy comedy film features a generous helping of sexual innuendo and adult language, and should definitely be considered NSFW (Not Safe For Work).

De Niro stars as a retired army general with a formidable libido who tricks his uptight grandson, Efron’s Jason, into driving him to spring break right before Jason is due to get married.

The film’s supporting cast includes former Parks And Recreation actress Aubrey Plaza, who also features heavily in the trailer, as well as Dermot Mulroney, Julianne Hough and Adam Pally.

Dan Mazer, co-writer of Borat and Ali G Indahouse, directs from a script by newcomer John Phillips. Dirty Grandpa will hit cinemas in the UK and the US on January 22.
