WATCH: Next Generation of Griswolds Hit the Road in ‘Vacation’ Trailer

It’s been more that 30 years since Chevy Chase’s Clark Griswold packed up his family and headed to Walley World in National Lampoon’s Vacation.

This weekend, the vacation continues when a grown-up Rusty Griswold, played by Office alum Ed Helms, packs up the family for a trip to the same theme park.

Vacation was written and directed by John Francis Daly and Jonathan M. Goldstein (Horrible Bosses), and stars Helms, Christina Applegate (Anchorman), Chris Hemsworth (Thor) and Leslie Mann (Knocked Up).

From the looks of the trailer, it looks like Chevy Chase has a cameo and Beverly D’Angelo is also back as Ellen Griswold.

The film opens in theaters on Wednesday, July 29.
