Natalie Portman has revealed that getting to strike Chris Hemsworth and Tom Hiddleston in the Thor sequel was "very satisfying".
The Oscar-winning beauty, who reprises her role as astrophysicist and Thor's love interest Jane Foster in Thor: The Dark World, got to give the Norse god a slap on the cheek. His brother Loki doesn't escape her violent streak either, as he finds himself on the receiving end of a neat right hook.
"It was very satisfying and cathartic. I feel like it's for the sisters," she said.
The 32-year-old mother-of-one added: "A lot of girls know what it feels like to not have someone call you back or just fall off the face of the earth. So it was a cathartic slap for all of us."
Natalie admitted that the scenes posed a logistical challenge, with Chris a foot taller than her 5ft 3in figure. Tom, too, stands almost a foot taller at 6ft 2in.
"There were secret boxes or ramps they would sneak in so I could be closer to him, otherwise there'd be no way I could hit his face. I'd be jumping and trying to reach his cheek," she said.
Despite the villainous threat posed by Malekith the Accursed (Christopher Eccleston) and his Dark Elves, there were light moments during filming.
"We all get along so well and we did a lot of laughing, maybe a bit too much laughing on set," the actress admitted.
"It's so fun to step onto a set where you already have friends. Often, first day at work can feel like you're going into the dining hall at school, and thinking, 'Which table shall I sit at?' To have friends who can make you laugh makes everything more comfortable right away."
