Amazon’s “ Red One ” is led by Chris Evans and Dwayne Johnson , two past winners of People’s Sexiest Man Alive, but one half-goat, half-heartthrob is stealing the show. “Game of Thrones” alum Kristofer Hivju plays Krampus, Santa’s surprisingly hot, devilish brother. He’s introduced halfway through the movie as Evans’ Jack O’Malley and Johnson’s Callum Drift are looking for the missing Santa Claus, played by an equally muscular J.

K. Simmons. Their search takes them to Krampus’ dark lair, where he’s surrounded by various mythical creatures playing “Krampusschlap” — a game with the goal of slapping your opponent across the room.

Despite being estranged from his brother, Krampus denies being part of the kidnapping plot that his ex-girlfriend and winter witch Gryla (Kiernan Shipka) has planned. However, Krampus can’t let Callum and Jack leave without playing Krampusschlap. Unfortunately for the hulking, yet hot, beast, Callum has some magic tricks up his sleeve, and the humans walk away free and (mostly) unscathed to continue their hunt for Santa.

Makeup artist Joel Harlow and specialty costume designer L.J. Shannon created the Krampus suit for Hivju, who flew back and forth from his native Oslo, Norway, to Los Angeles for fittings over several months.

“First we made a sculpture of my whole body, and then they made suits around it. When I flex my muscles, it has reactions in the suit,” he said. He compared the 85-pound, full-body suit to Colin.
