Christina Applegate is in final talks to join the cast of New Line Cinema's Vacation reboot, alongside Ed Helms.

The story is essentially a hybrid of a sequel and a reboot, with Ed Helms portraying a grown-up Rusty Griswold, who takes his own family on a vacation to Walley World, just like his childhood trip portrayed in 1983's Vacation. Christina Applegate will play Rusty's wife who may be losing interest in her husband.

The character Rusty Griswold was portrayed by a number of very different actors throughout the original franchise, including Anthony Michael Hall in Vacation, Jason Lively in European Vacation, Johnny Galecki in Christmas Vacation, and Ethan Embry in Vegas Vacation.

The Incredible Burt Wonderstone writers John Francis Daley and Jonathan M. Goldstein will make their directorial debuts, working from their own screenplay. It isn't known when production will begin.

Christina Applegate is currently shooting Anchorman: The Legend Continues in Atlanta.
