Anne Hathaway has confessed she was crippled by nerves performing her big number I Dreamed A Dream on the set of Les Miserables.
The actress plays tragic heroine Fantine in the musical and revealed director Tom Hopper tried to play down the famous song to put her at ease.
Anne explained: "It came right after I cut off my hair so it was a little bit of an intense one-two punch. It wasn't my favourite scene to shoot just because there was so much pressure of expectation.
"I had gone to Tom and said I was starting to feel nervous about a week before. He said, 'Listen. It's not an iconic song. You mustn't think about it like that. It's this woman's howl. It's her processing what's just happened to her.'
"But I couldn't stop thinking about how if I messed it up how exposed I would feel.
"So I did the first take and I was so angry with myself because it wasn't good enough. I dug in a little deeper and we did the second take and it wasn't there and I just thought, 'Oh, God.' I started the third take and I just said, 'No, no. Stop. I'm sorry. The balance, it's off.'
"And that's when I took the earpieces and stuck them in my ears. I closed my eyes and I remember thinking, 'Hathaway, if you do not do this in this moment, you have no right to call yourself an actor. Put aside all that bulls*** and just do your job.' I opened my eyes and I'm like, 'Let's go.' And I did it. That was the one that I let rip and that was the one that was in the piece."
Les Miserables opens in the UK on January 11.
