The long in-the-works Vacation reboot just cast its grown-up Audrey. Variety reports that Leslie Mann has signed on to star opposite Ed Helms and Christina Applegate as Rusty’s sister Audrey Griswold, who was played in the original 1983 film by Dana Barron. In addition to Mann’s casting, child actors Skyler Gisondo and Steele Stebbins have been cast as Rusty’s (Helms) sons in the reboot, both Chris Hemsworth and Charlie Day are in talks to show up in small roles, and original Griswolds Chevy Chase and Beverly D’Angelo will both make cameo appearances.
