Rinko Kikuchi has told of how much respect she has for Keanu Reeves, because he is focused on his work.
The Japanese actress - who starred in the acclaimed Norwegian Wood and appears in new action blockbuster Pacific Rim - worked with The Matrix star on Samurai movie 47 Ronin, due out later this year.
She said: "It was fantastic working with Keanu. I love him, and I really respect his work.
"He was always really concentrated on his performance, and I really respect that."
In Pacific Rim, Rinko plays Mako Mori who works with a team of pilots who power giant robots to fight monsters who have invaded the world.
Mako is one of only a couple of women in the team.
Rinko said: "I love that she's totally butt ass and she's brave and she's tough she can face her trauma, I love this role!
"Most of the set was real so I felt like I became a true pilot and I felt always like this is a real fight."
:: Pacific Rim opens in cinemas on Friday July 12.
