Ellen Page has revealed that her starring role in a computer game is her "most challenging acting job" to date.
The 26-year-old underwent months of motion capture sessions to shoot numerous scenes and alternative outcomes for the new video game Beyond: Two Souls, which sees her being transformed into a computer-generated image of lead character Jodie Holmes.
"I didn't know how to wrap my head around it. I mean, what does it mean to be in a video game? I had no concept. I hadn't played anything in like ten years," she told Metro.
"To have the opportunity to play her and have an experience like this is unlike anything I've done before. With a movie, you might shoot a page a day. With a video game, you don't really know what you're walking into."
Ellen continued: "I had a 2,000 page script and every day we'd shoot 30 to 40 pages. It was absolutely the most challenging acting job, a really, really emotionally intense and gruelling experience."
The star of movies such as Juno and Whip It also adapted to wearing the motion capture suit: "Wearing the sensors was strange at first - you can't physically touch your face and I thought, 'What if something is emotional and I'm crying?' But in the end it was kind of nice just coming into work and putting on my little suit without having to go through hair and make-up."
Ellen has been filming the X-Men sequel - Bryan Singer's X-Men: Days Of Future Past - in Montreal, where she reprises her role of Kitty Pryde.
"I love getting to be Kitty Pryde. We started shooting a couple of weeks ago so it's early days but the movie's going to be huge," she said.
