Robert De Niro and spring break aren't exactly a match made in heaven.
Throw in Zac Efron, whose 2015 dance music drama We Are Your Friends tanked at the box office and the recipe doesn't look pretty for new film Dirty Grandpa.
De Niro has been criticised by some fans
for taking on soft roles such as his lastest performance in The Intern.
He famously walked out of an interview promoting the comedy after Britain's Radio Times journalist Emma Brockes asked how he resisted the temptation to go into "autopilot" mode on set.
Dirty Grandpa is written by John Phillips and directed by longtime Sacha Baron Cohen collaborator Don Mazer, who earned an Oscar nomination for his work on Borat.
