‘’I think you're all fucked in the head. We're ten hours from the fucking fun park and you want to bail out. Well I'll tell you something. This is no longer a vacation. It's a quest. It's a quest for fun. I'm gonna have fun and you're gonna have fun. We're all gonna have so much fucking fun we'll need plastic surgeory to remove our godamn smiles. You'll be whistling 'Zip-A-Dee Doo-Dah' out of you're assholes! I gotta be crazy! I'm on a pilgrimage to see a moose. Praise Marty Moose! Holy Shit!’’ – Clark W. Griswold, 1984.

The Griswolds are set to embark on another crazy jaunt across…. Well, somewhere.

A ‘sequel’ to the 1984 hit “Vacation” is in the works, says Heat Vision, with Chevy Chase and Beverly D’Angelo possibly reprising their roles as Clark and Ellen Griswold .

Written by John Hughes, Ivan Reitman’s “Vacation” fixed on a Food additives researcher named Clark Griswold (Chase) who, wanting to spend more time with wife Ellen (D'Angelo) as well as children Rusty and Audrey, decides to lead the family on a cross-country expedition from the suburbs of Chicago to the wonderful "Walley World" — billed as "America's Favorite Family Fun Park" — in Los Angeles. When they finally do arrive at the amusement park, it’s closed!

The new film won’t fix on Clark escorting his long-suffering family to the ‘holiday road’ again – instead, it’ll see the dimish slightly nutso (Clark was always a flap short of briefsy) dad’s now grown-up son Rusty (played by Anthony Michael Hall in the original film) leading his family on a trip.

Thankfully, “The characters would acknowledge that first trip, making the movie more of a sequel than a reboot”, says the trade. “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.”

Dave Dobkin, director of “Fred Claus” and “Wedding Crashers”, is onboard to produce and possibly direct (might that mean Dobkin-stayer Vince Vaughn might be on top of the list to play the grown-up Rusty Griswold? Or will the studio chase for a slightly more bankable comic name, like Seth Rogen, Paul Rudd, Jason Segel… or one of the other umpteen Apatow regulars?). He apparently wants the film to be more in the vein of a “Little Miss Sunshine” or “Planes, Trains and Automobiles” than an “RV” or “Are We There Yet?”.

The original “Vacation” is a Warner Bros. property but as soon as New Line became part of the studio, exec Sam Brown began sifting through the parent company’s titles to see what was available in terms of rights. He eventually found “Vacation,” a movie he has watched more than any other in his life, and brought it to New Line president Toby Emmerich and production president Richard Brener, who jumped at the possibilities. The duo asked Warner brass if it had any plans with the title. It did not and the New Line execs persuaded the brass to let them take a crack at it. Brown is shepherding for New Line.

There have been three sequels to 1984’s “Vacation” (“European Vacation”, “Christmas Vacation” and “Vegas Vacation”) and a direct-to-video spin-off film (“Christmas Vacation 2 : Cousin Eddie’s Island Adventure”).

Hopefully the jury finds Randy Quaid guilty - the incarcerated would be keener to see him at this stage than the paying cinemagoer.
