The 29-year-old actress, who got a dramatic short pixie crop for her part as Fantine in the film, is happy with new look, reported Contactmusic.
"I did it for a film, so it really wasn't about me and my security. I'm just so pleased with how I look, so I now quite like having short hair," Hathaway said.
The "Dark Knight Rises" actress also said that initially she had some reservations about singing Fantine's legendary tune, 'I Dreamed a Dream.'
"That's actually the thing we talked about when I first came in to film. I apparently looked like I was ready to face the guillotines. They just kept telling me and the cast to ignore the iconic nature of Les Mis and of the song. I had to sing it as if it had never been sung or heard before," she said.
