Dan Mazer's 'Dirty Grandpa' Planned for Blu-ray

The comedy starring Robert De Niro and Zac Efron will hit the high-definition road in April.

In an early announcement to retailers, Lionsgate is preparing 'Dirty Grandpa' for Blu-ray on April 26.

Being bad has never felt so good as Robert De Niro and Zac Efron get down and dirtier in this outrageously funny unrated version of Dirty Grandpa! Uptight Jason (Efron) is a week away from marrying his boss's daughter. But everything changes when Jason's fooled into driving his foul-mouthed, free-living granddad (De Niro) to Florida for spring break-and thrown into a series of frat parties, bar fights, and epic misdeeds on a road trip that gives new meaning to family bonding.

Specs have yet to be revealed, but supplements will include: The Filthy Truth: The Making of Dirty Grandpa" Featurette; "Daytona Heat" Featurette; "Filthy Filmmakers Who Have No Shame" Audio Commentary; "Lessons in Seduction" Featurette; "I Got Nothin' to Hide: A Look at Daytona's Most Vibrant Drug Dealer" Featurette; and Gag Reel.
