Zac Efron and Robert De Niro are attached to star in “Driving Dick Kelly,” an adult comedy formerly known as “Dirty Grandpa” that Dan Mazer will direct for Bill Block‘s QED International, TheWrap has learned.
John Phillips wrote the script, which follows a lascivious, recently widowed Army veteran (De Niro) who tricks his uptight grandson (Efron) into escorting him to Florida for spring break.
