Actress Anne Hathaway has revealed that she was not happy after winning an Oscar in 2013 for "Les Miserables". The 33-year-old actress won the honour for her role of a prostitute named Fantine in "Les Miserables" and she said she was forced herself to smile after the win, reported Guardian. "I felt very uncomfortable. I kind of lost my mind doing that movie and it hadn't come back yet. Then I had to stand up in front of people and feel something I don't feel which is uncomplicated happiness," Hathaway said. "It's an obvious thing, you win an Oscar and you're supposed to be happy. I didn't feel that way. I felt wrong that I was standing there in a gown that cost more than some people are going to see in their lifetime, and winning an award for portraying pain that still felt very much a part of our collective experience as human beings." She added, "I tried to pretend that I was happy and I got called out on it, big time. That's the truth and that's what happened. But what you learn from it is that you only feel like you can die from embarrassment, you don't actually die."
