Thor 2: Kiss And Tell

As it turns out the kiss in that post-credits tag in "Thor: The Dark World" wasn't between Thor (Chris Hemsworth) and astrophysicist Dr. Jane Foster (Natalie Portman) after all.

A scheduling conflict meant Portman and Hemsworth couldn't be in the same space together to lock lips kiss, so someone had to step for Portman.

Hemsworth's own wife Elsa Pataky got the job

Portman tells the NY Daily News:

"It was for reshoots [after the film was finished] and he was working in Hong Kong and I couldn't get there because I was working on my own film. And so they put his wife in my wig and costume. That's why it was so passionate."

A combination of angles, makeup and costumes helped Pataky become Foster.
