Billed as a sequel to the 1983 cult classic National Lampoon's Vacation, this comedy adventure, simply titled Vacation, stars Ed Helms and Christina Applegate. It sees the Griswolds return to Walley World at last - only this time, they're led by the grown-up Rusty (Helms), who wants to relive his childhood and create some much-needed family bonding time with a fun-filled trip to the theme park.

But, this being a National Lampoon film, the road trip doesn't go without a bump, with plenty of chaos and risque comedy along the way, including a delightful family swim and underwear that leaves little to the imagination.

The cast also features Thor himself - Chris Hemsworth - taking a welcome foray into comedy, alongside Charlie Day (Horrible Bosses), Leslie Mann (Knocked Up) and original Lampoon stars Chevy Chase and Beverly D'Angelo. Skyler Gisondo and Steele Stebbins play the Griswold kids.
