"I'd like to do my best when it comes to setting a decent example to younger women," she told Vanity Fair when asked about the #MeToo movement.
She said early on her career she experienced an inappropriate comment onset from a crew member when she starred alongside New Zealand actress Melanie Lynskey in Heavenly Creatures.
Winslet explained to Vanity Fair: "I remember his name, and he really was a nice guy, but when you're younger, you do this nonsense thing of just thinking, 'That's what men say.' And they do it sometimes like they're breathing ... I don't know a single girl, actually, who hasn't experienced some level of harassment on that level. Even if they're just words, they're so powerful. It's like bullying."
The Titanic actress is currently promoting her new movie Ammonite, where she stars alongside Saoirse Ronan (Lady Bird). Set in 1840s England, she plays real-life palaeontologist Mary Anning, and Ronan plays a married geologist. The pair work together and form a close bond, leading to a romantic - but forbidden- relationship.
