LONDON (AP) -- Natalie Portman says hitting Chris Hemsworth was "one small slap for womankind."
The actress, who reprises her role as Jane Foster in "Thor: The Dark World," gives the superhero a smack in the Marvel sequel.
"Thor: The Dark World" has its world premiere in London Tuesday and is out in U.S. cinemas Nov. 8.
At a promotional event on Saturday, Portman said that she channeled all her single girlfriends: "You hear all these stories about guys and it's just good to get a nice on-screen slap like 'you didn't call me back.'"
The intention may have been payback but, according to Hemsworth, the result was less so.
"It just got really funny and ridiculous you know. It's like in high school when you're not meant to laugh," he said.
