Photos from the Atlanta set of "Vacation" starring Ed Helms and Christina Applegate

The project isn't a remake, exactly. Rather, as Variety notes:

"Helms is starring as Rusty Griswold, the grown-up son of Clark Griswold (portrayed by Chevy Chase in the 1983 film), who takes a family trip similar to the one he took as a boy.

(Leslie) Mann will play Rusty's sister Audrey Griswold, who was played by Dana Barron in the 1983 original.
