Chris Hemsworth, Skyler Gisondo & Ed Helms in Vacation (2015)

This year's return to the Vacation franchise brings Ed Helms into the story as an adult Rusty Griswold, who looks to reconnect with his family by taking a trip to the famed Walley World. Skyler Gisondo stars as Rusty's teen son James. Both actors get shirtless for a trip into a hot springs that they don't realize is actually a sewage dump. Chris Hemsworth plays Stone Crandall, the perfect husband of Rusty's sister Audrey. When the Griswolds spend the night with the Crandalls, Chris strips down to his underwear, showing off Stone's good lucks and comically-large penis, which makes Rusty uncomfortable. The extended sequence allows Chris to show off his great body.
