Michael Fassbender flipped off at Sophie Turner the first time he met her.
The Game of Thrones actress was "nervous" about meeting the 39-year-old actor when she joined the cast of X-Men: Apocalypse but knew they'd get on well when he greeted her with a rude gesture.
She said: "I was also about meeting Michael Fassbender, but [on my first day on set] I looked over and he gave me the middle finger, jokingly, and I thought, 'We're going to get on.' "
Sophie also got on well with "down-to-earth" Jennifer Lawrence and the Joy star even looked after her when she fell ill.
She told Britain's Marie Claire magazine: "Despite being one of the most famous actresses in the world, she's so down to earth. One day I got sick and she was looking after me, constantly checking up on me, getting me tablets. She was like a big sister."
