Zac Efron and Robert De Niro have gone coastal.
Their movie "Dirty Grandpa" first filmed in metro Atlanta earlier this year before heading eastbound and down. They've been filming at Tybee Island.
The movie is about a guy (Zac) who takes his lewd gramps (Bob) on a spring break trip to Florida (Tybee).
Apparently the plot involves time travel back to about 1988. Check out these neon britches and Flashdancey crop top!
