Don't mess with Olivia Munn
Don't pick a fight with Olivia Munn.
The US actress displayed some expert moves with a katana - a Japanese-style sword - in a video she shared on Instagram.
"Learned some new tricks," she captioned, which showed her expertly twirling a sword as part of her preparation to play Psylocke in X-Men: Apocalypse.
Her ninja-like mutant has powers of telepathy, telekinesis and precognition, and her signature weapon is a katana, naturally.
Also featured in the video is her boyfriend, National Football League star Aaron Rodgers.
