Actors Zac Efron and Robert De Niro will reportedly be seen in `Dirty Grandpa`, a comedy.

Efron, 26, is set to play a young man who is tricked by his grandpa, a perverted former army general played by De Niro, to travel to Florida for spring break, reports hollywoodreporter.com.

This is their second film together, following the 2011 ensemble flick `New Year's Eve`.

`Dirty Grandpa` is to be written and directed by Dan Mazer, who is perhaps most famous for his collaborations with `Borat` creator Sacha Baron Cohen.

The studio is yet to confirm a release date for the project.
