Zac Efron teaming up with Robert De Niro for comedy film

Zac Efron and Robert De Niro are teaming up to star in new adult comedy Driving Dick Kelly.

The film stars De Niro as a recently widowed, salacious army veteran who manages to trick his uptight grandson, played by Efron, to drive him to Florida for spring break.

According to TheWrap.com, veteran actors Jeff Bridges and Michael Douglas were also up for the role that eventually went to De Niro.

Efron, who performed an impersonation of De Niro in college comedy Neighbors earlier this year (14), previously starred in 2011's New Year's Eve with the legendary actor, but the two did not share any scenes together.
