Emily Blunt had a "full-on anxiety attack" after watching Natalie Portman in 'Black Swan'.

The 27-year-old British actress plays a ballerina in new movie 'The Adjustment Bureau' and admits that even after months of training, she didn't master the craft as well as Oscar-nominated Natalie did in the recent dance-based thriller.

She said: "I literally had never done it before in my life. I had to do four months of boot camp, swept out of my comfort zone. I've got calves of steel.

"I had a full-blown anxiety attack watching 'Black Swan'. It was extraordinary what Natalie did - spooky good."

As well as taking dance lessons, Emily also taught herself how to run in a different way following advice from co-star Matt Damon.

She admitted: "Matt's given me good advice - 'make sure you watch yourself on playback. You might run like an idiot and not know it.'

"I had this chicken-arm flapping about. Thank God I caught that."
