Olivia Munn was unconvinced she could become

The 37-year-old starred as Psylocke in the 2016 superhero film, and Munn said the experience has given her a thirst for more action roles, reports femalefirst.co.uk.

"I really didn't realise how much I loved doing it until I actually was training for X-Men," Munn said,when asked what attracts her to do action parts.

She added: "When I signed on for X-Men, I wasn't sure if I wanted to do it and I was talking to (screenwriter) Simon Kinberg, and he was like, 'This is the introduction of the character, so it's going to be a smaller part and for this movie...' She told: "I sort of didn't realise that I would have to do so much training for it until I got there and I realised that my stunt double, who had never been a stunt double before".

"And I said, 'Well, that's cool as long as you could just have a fight scene'. And to me, I grew up loving her so I know that they really didn't do her justice the first time that she was introduced". And I'd watched it and I was like, 'This is stupid'. The first time I saw it, I thought, 'You have to give her more,' "And so then, since I have a background in martial arts and gymnastics and I cared so much about the fight scene for the character, I started training every day".However, Munn did not initially appreciate just how much hard work was needed to star in an action film.
