Portman risked breakdown for Swan
Natalie Portman has revealed training for her Oscar-winning role in Black Swan left her on the verge of a breakdown.
The 29-year-old actress - who is expecting her first child this summer with choreographer fiance Benjamin Millepied - told The Sun playing scientist Jane Foster in Kenneth Branagh's comic book movie Thor helped her recover from the strain of making the ballet thriller.
Natalie said: "It probably delayed the onset of a total breakdown from the efforts of doing Black Swan, which is going to hit at any moment."
She went on: "We got nice long breaks and I got to read in my trailer which was very comfortable and has a bed. I could eat whenever I wanted and train whenever I felt like it.
"Also I went on to do the Ivan Reitman comedy No Strings Attached as well. They didn't require a lot of research ahead of time.
"They didn't require any specific physical training. Both were very fun projects, surrounded by friends.
"They were both the gentlest of any work experience I could have gone into after the extreme situation of doing Black Swan."
The Leon star was delighted to work with Branagh and enjoyed playing Chris Hemsworth's leading lady, but joked she only got the part because of her height.
She said: "He's a god. I think that was why I was cast - 'She'll make anyone look big!'"
