Alicia Vikander turned blue filmingTomb Raider: 'The cold, that's the tough thing'

And EW has an exclusive behind-the-scenes peek at the Oscar-winning actress hard-fought transformation into the video game heroine.

She was extremely fierce and capable and a big adventurer.

This film is about her becoming the action hero that we know her to be.

Bruises and the hits, you kind of just suck up.

But the cold, that is the tough thing.

We had water cannons being thrown at us.

We even had to reshoot some things because I turned too blue.

I always wanted to try all these physical action beats.

Now, I feel like I have the strengths.

And I go to the gym five days a week.

Tomb Raidervaults into theaters March 16.
