Actress Kate Winslet, who won Best Supporting Actress at the BAFTA, said she was once told by a drama teacher to "settle for the fat girl parts".
The Titanic star, 40, dedicated her award, which she won for playing Apple marketing executive Joanna Hoffman in Steve Jobs, to women who are the subjected to criticism.
"When I was younger, when I was 14, I was told by a drama teacher that I might do OK if I was happy to settle for the fat girl parts," Kate said in her acceptance speech.
"So, what I always feel in these moments is that any young woman who has ever been put down by a teacher, by a friend, by even a parent, just don't listen to any of it, because that's what I did. I kept on going and I overcame my fears and got over my insecurities," she said.
It was Kate's third BAFTA win, after winning awards for Sense and Sensibility (1996) and The Reader (2009). She beat out competition from fellow actresses Julie Walters and Rooney Mara.
Kate is also nominated for an Oscar for her role in the Danny Boyle-directed biopic of the Apple boss. If she wins, it would be her second Academy Award.
