Robert De Niro and Zac Efron have been reportedly cast in new comedy, Dirty Grandpa.
26-year-old Efron will play a young man who is tricked by his grandpa - a perverted former army general played by 71-year-old De Niro - to travel to Florida for spring break, according to Variety.
Dirty Grandpa would mark the second time the pair have appeared on the big screen together, following the 2011 ensemble flick New Year's Eve.
The comedy is to be written and directed by Dan Mazer, who is best known for his collaboration with Borat creator, Sacha Baron Cohen.
