It's Time For Another VACATION!!

Merrick here...
New Line is dusting off the VACATION franchise previously branded by National Lampoon.

New Line is meeting with writers to write the script but the take is already developed: the story focuses on Rusty Griswold, the son of Clark Griswold, the protagonists of the initial movies and portrayed by Chevy Chase. The younger Griswold is now a father in his own right and takes his family on a road trip vacation. The characters would acknowledge that first trip, making the movie more of a sequel than a reboot. Chase and Beverly D’Angelo, who played the mom in the original movies, will have room to make appearances as grandparents, providing a sense of continuity, though no deals are in place. [EDIT] New Line is taking meetings with writers this week, hoping to make a movie that skews more towards “Planes Trains and Automobiles” or “Little Miss Sunshine” than “RV” or “Are We There Yet?”

..says THR HERE. "Rusty" was played by Anthony Michael Hall in the first VACATION film, Jason Lively in EUROPEAN VACATION, Johnny Galecki in CHRISTMAS VACATION, and Ethan Embry in VEGAS VACATION. Perhaps, as an in-joke, The Powers That Be could pull an IMAGINARIUM OF DOCTOR PARNASSUS & have Rusty played by multiple actors in this new film.
