Chris stars in the rebooted comedy classic and it was a family affair on Monday night (27 July), as he was joined by his nearest and dearest at the premiere in Los Angeles.
Looking ever so dapper, Chris, Luke and Liam joked around on the red carpet before posing for photos.
Chris also engaged in some PDA when he was joined by his actress wife Elsa. The 39-year-old, who looked stunning in a frilly pink lace dress, has three children with Chris - daughter India Rose and twin sons, Tristan and Sasha.
Chris plays Stone Crandall in Vacation. The movie focuses on Rusty Griswold (Ed Helms) and his misadventures as he takes his family to Wally World before the theme park permanently closes.
Chris has come a long way since his days in Home and Away, where he played school boy Kim Hyde from 2004 to 2007.
He made his transition from soap star to Hollywood hunk when he landed the role of Thor in Marvel films Thor (2011), The Avengers (2012), Thor: The Dark World (2013) and Avengers: Age of Ultron (2015).
Having also landed roles in Snow White and the Huntsman and Red Dawn, along with a Sexiest Man Alive title under his belt, Chris has become one of Home and Away's most successful alumni's.
