Chris Hemsworth didn't have to fake anything during the filming of Thor: The Dark World, especially while shooting its memorable love scene.
His costar Natalie Portman revealed that when she couldn't make it back to the Marvel set for a pickup shoot, the Aussie hunk's real-life wife, Elsa Pataky, put on a wig and filled in for her as Dr. Jane Foster during their big kissing scene at the end of the credits.
"It was for reshoots and he was working in Hong Kong and I couldn't get there because I was working on my own film," Portman told the New York Daily News. "And so they put his wife in my wig and costume. That's why it was so passionate."
Pataky, 37, is no stunt double.
The Spanish beauty has been acting since 1997 and had a plum role in 2011's Fast Five. So standing in for Portman was a piece of cake for the actress, which explains why the Thunder God's final smooch with Foster had so many sparks—because the chemistry was real.
And moviegoers had not a clue thanks to the magic of moviemaking.
"It was such a perfect solution, wasn't it?" added Portman.
Pataky and Hemsworth began dating in early 2010 not long after Elsa ended a three-year relationship with Oscar winner Adrien Brody. The two tied the knot in December 2010 and later welcomed their first child, daughter India Rose, now 18 months. Just last week, Hemsworth's rep confirmed to E! News that the couple is expecting their second child.
