Chris Hemsworth, Leslie Mann could join "Vacation" sequel cast

There's going to be a couple of new additions to the "Vacation" family.

"The Other Woman" actress Leslie Mann and "Thor" star Chris Hemsworth are in talks to join the cast of the new comedy sequel, according to The Hollywood Reporter.

"It's Always Sunny in Philadelphia" star Charlie Day has also reportedly entered negotiations for a role.

"Vacation" will serve as the latest installment in the popular film series, which was originally based on stories from National Lampoon magazine.

Chevy Chase starred in the first outing, 1983's "National Lampoon's Vacation," written by John Hughes (based on one of his short stories) and directed by late "Ghosbusters" star Harold Ramis. Chase played the dim-witted but lovable patriarch Clark Griswald, who just wanted to take his wife Ellen (Beverly D'Angelo) and kids (Anthony Michael Hall, Dana Barron) on a cross-country road trip to the fictional theme park, Wally World. Unfortunately for Clark, not a single thing seems to go right on the trip.

The film was well-received, grossing over $60 million in the U.S. alone, a high figure for a comedy at the time.

Three more sequels followed, with Chase and D'Angelo reprising their roles, while their children were recast from film to film with new actors. The last sequel released in the series was 1997's "Vegas Vacation," which was panned by critics and audiences.

There was also a made-for-TV spinoff film, 2003's "Christmas Vacation 2: Cousin Eddie's Island Adventure," which starred franchise regular Randy Quaid in the title role. Barron also returned for the TV movie and reprised her role as Audrey, the daughter of Clark and Ellen, although Chase and D'Angelo did not appear.

Mann, who is the wife of Judd Apatow, is reportedly set to take over the role of Audrey, while Hemsworth will play her TV-anchor husband.

The new "Vacation" film will focus on Audrey's brother Rusty, here played by Ed Helms, and his family, as they embark on yet another ill-fated adventure. "Anchorman" actress Christina Applegate will play Helm's wife.

Fans of the original will also get to see Clark and Ellen reunited. Chase and D'Angelo have agreed to make appearances in the new film.

A release date has yet to be announced.
