"We met on a plane going to Comic-Con," Charlize revealed to E! Online. "You know when you meet someone and it's effortless? It was instantly amazing."

"We couldn't shut up," she continued. "The plane landed and they were like, 'Get off the plane' and we were going on and on."

The friendship stayed the same on the set of the movie. "I think we both love what we do and we came to play," Charlize said.

Awww... sounds like the beginning of a beautiful friendship!
