Swedish actor Alicia Vikander says the extreme stunts she completed for the new Tomb Raider movie, left her "crippled."

"At first, it hurts. So much so that you can't walk or get out of bed for the first three weeks. I was, like, crippled. I had pain places I didn't know existed," she adds.

Vikander's version of Lara Croft is not the pin-up character associated with the video game or Angelina Jolie's take on the character. The actor thinks it was important to show her alter ego as more than just a sex symbol.

"It's not just the character of Lara Croft, it's society that's changed. I think what we actually express as being extremely attractive or sexy is just different. Even young boys or girls on the street wouldn't comment, 'Oh, a pair of shorts is what I find sexy'. It's actually changing, which is a lovely thing," says Alicia.

"People say, 'Oh you don't want to make her sexy?' No, I want to make a young woman who is sexy, but I want her to be fierce, cool, witty, funny. I want her to be somebody you want to hang out with, as a woman and a man. Society's changing so this is more in line with what we find sexy today," she adds.
