Dirty Grandpa is a 2016 American comedy directed by Dan Mazer. Robert De Niro stars as Dick Kelly, a recently widowed retired Army Special Forces officer who manipulates his uptight, button-down grandson Jason, played by Zac Efron, into driving him to Daytona Beach for spring break — ostensibly to pay respects at a veteran's memorial but actually to get drunk, smoke weed, and pursue college women, particularly a young woman played by Aubrey Plaza. The film's comedy was built on the disconnect between Robert De Niro's distinguished cinematic legacy and the relentlessly crude, sexually explicit humor his character engaged in — a contrast that some audiences found hilarious and many critics found uncomfortable.

Aubrey Plaza's openly aggressive pursuit of De Niro's Dick provided the film's most quotable moments. Dirty Grandpa earned $104 million worldwide on a $11 million budget.
