Warner Bros. has finally released the first official trailer for the highly anticipated “Vacation” reboot. The two and a half minute clip features plenty of hilarious moments, guaranteed to leave you in stitches, but it’s Chris Hemsworth’s NSFW cameo that you’ve just got to see to believe.

The trailer begins by paying homage to the original National Lampoon film with an appearance from legendary funnyman Chevy Chase – the original Clark Griswald. With Rusty Griswald (Ed Helms) now tasked with leading the unconventional family, the Griswald’s set out to “shake things up” by hitting the open road.

“We’re driving to Wallyworld,” Rusty declares.

While there are some familiar faces, names and place – Clark, Wallyworld, and the infamous girl in the red sports car – we assure you this family vacation is one of a kind. During their drive across country Rusty and the crew encounter no shortage of strange characters and uncomfortable situations, but none are more noteworthy than their run in with Chris Hemsworth’s incredibly well-endowed character, Stone Crandall, which can be seen about two minutes in. Go on – skip ahead, we know you want to.

The 80s remake, which marks the directorial debut of John Francis Daley and Jonathan Goldstein, boasts an incredible cast of characters. Joining Helms and Hemsworth on the silver screen is Christina Applegate, Leslie Mann, Nick Kroll, Charlie Day and a whole new cast of young characters as the new generation of Griswald children. Much like the first film, “Vacation” has been rated R.

“Vacation” hits theaters everywhere July 29. Check out the trailer below.
