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."
The 20-year-old star was signed to the next instalment of the superhero film late last year and has admitted she burst into tears as soon as she received the call from her management telling her she'd secured the gig.
Asked what she did as soon as she found out, she explained: "I rang my mum and she started crying, then I started crying. It was crazy. Then my phone started blowing up."
