Olivia Munn was unconvinced she could become an action star

Olivia Munn says she was not convinced she was suited to do action roles until she starred in X-Men: Apocalypse.

The 37-year-old starred as Psylocke in the 2016 superhero film, and Munn says the experience has given her a thirst for more action roles. "I really didn't realise how much I loved doing it until I was training for X-Men," says Munn, when asked what attracts her to action parts. 

She adds, "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...' 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 much that I know that they really didn't do her justice the first time she was introduced."

However, Munn says that she did not initially appreciate how much hard work was needed to star in an action film.
