The actress said in a new interview with The Guardian that the criticism may have been deserved.
When she won the best supporting actress award for her role as Fantine in "Les Misérables," Hathaway said, she 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. It's an obvious thing — you win an Oscar, and you're supposed to be happy. I didn't feel that way," she said.
"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. I tried to pretend that I was happy, and I got called out on it, big time."
Hathaway, 33, is now starring in the film "Colossal" and raising her 6-month-old son, Jonathan. Motherhood, she added, has been all-consuming.
"I'm feeding a child from my body," she said when asked if she has seen any new superhero films lately, "and that takes up all my time."
