Chris Hemsworth and Charlie Day are in negotiations to join the cast of the reboot of the "National Lampoon's Vacation" franchise starring Ed Helms and Christina Applegate.
John Francis Daley and Jonathan Goldstein ("Horrible Bosses") penned the script and are still attached to direct the project which was delayed last year due to script work.
Ed Helms plays the grown-up version of Rusty Griswald who now has a family of his own and gets up to misadventures on the road. Day will play a river raft touring guide.
Hemsworth will play Audrey's boyfriend, an up and coming anchorman. He'll shoot his role before jumping onboard Universal's "The Huntsman" which he'll film early next year.
