English actor Kate Winslet says she felt bullied after the global success of her 1997 release Titanic, because the film brought her personal life into scrutiny.

Winslet became a household name at the age of 21 after the success of the James Cameron film that cast her as Leonardo DiCaprio's romantic lead. Now, in the podcast WTF, the actor has spoken about the aftermath of her breakout role in her personal life.

"I went into self-protective mode right away (after Titanic came out)," Winslet said, adding: "It was like night and day from one day to the next. I was subject to a lot of personal physical scrutiny, I was criticised a lot and the British press were quite unkind to me."

"I felt bullied if I'm honest. I remember thinking, ‘this is horrible and I hope it passes' -- it did definitely pass but it made me realise that, if that's what being famous was, I was not ready to be famous, definitely not," she shared.

At that time, instead of cashing on her newfound fame, she decided to hone her craft.

"I still felt like I wasn't really ready to do lots of big Hollywood jobs. It was a huge responsibility. I didn't want to make mistakes, I didn't want to blow it -- I wanted to be in it for the long game. So I did strategically try and find smaller things, just so I could understand the craft a bit better and understand myself a bit better, and maintain some degree of privacy and dignity," Winslet said.

Winslet recently starred in the 19th century period drama Ammonite, as real-life paleontologist Mary Anning, who falls madly in love with a young woman (Saoirse Ronan).
