Efron, De Niro for road trip film
Zac Efron and Robert De Niro could be going on a road trip together for a new movie.
The actors are both in early talks to star in raunchy comedy Dirty Grandpa, according to the Hollywood Reporter.
De Niro, 71, would play the titular character, a perverted and vulgar former Army General, who thinks his grandson is about to tie the knot with someone who is wrong for him.
Efron would play the uptight grandson, who finds himself conned into driving his grandfather to Florida for spring break.
The 26-year-old actor has previously showed off his comedy chops in films such as That Awkward Moment and Neighbours.
Dan Mazer will direct Dirty Grandpa and Barry Josephson will produce.
