Ali Larter went on a huge learning curve whilst shooting Resident Evil: Afterlife.
The actress reprises the role of Claire in the four movie of the franchise as she once again joins forces with Milla Jovovich.
But it's the first 3D movie for the Heroes star as it was a whole new way of filming for the actress.
Speaking to Collider she said:" It’s definitely been the biggest learning curve for me. As an actor, whenever I start on a movie, different things that I perform in ask for different skill sets.
"And this one is definitely the technological side of it. You have to hit your mark. You can’t weave back and forth because your nose is jutting at you in 3-D. It’s really been learning how to do that and also it’s exciting to be on the forefront of this technology.
"This Phantom Camera is incredible. I’ve watched some of the dailies. It is just, it raises this tension. It makes everything so sensorial and, it’s just thrilling to watch.
"The payoff is we can see that it’s worth it. Within that, you’ve got to hit your mark. I defer to whatever the cameraman or Paul needs within the shot. And you always, you do, you keep your energy up and know that the outcome is going to be worth it.
Resident Evil:Afterlife is released 10th September.
