Keira Knightley has admitted that she considered giving up her movie star career in her early 20s due to the pressure she came under following her rise to fame.

The now 33-year-old actress was just 17 when she became famous for her role in Bend It Like Beckham, before going on to star in hugely successful movies such as Love Actually and Pirates Of The Caribbean, which propelled her to global stardom.

Knightley revealed in October that she had been diagnosed with post-traumatic stress disorder (PTSD) at the age of 22, and has now said that she almost gave up her whole career during that period.

She told The Sunday Times' Style magazine that her friends and family wanted her to give it up, and said: "I did think about it. Particularly at the point when I had a breakdown.

"I had PTSD and panic attacks. I literally couldn't work for a year and I didn't know whether there would be an end to that.

"I have a super-solid background and thank f*** for that. My family and my small but very close group of friends just wrapped me up. And I think, without that, it would have been a very different story."

She added: "I knew I always had somebody there to cuddle me who didn't want anything from me. Ultimately I didn't want them (the media and paparazzi) to win. The only thing I want to do is make films."

The Oscar-nominated actress also said that she misses going out now that she is a mother. Knightley and husband James Righton had daughter Edie in 2015.

She said she "loved" going out in her younger days, and added: "I felt like a big part of myself was the self that was out dancing until six in the morning most nights unless I was on a film.

"That's a difficult shift for any couple when you have a child. I don't think we would have survived physically for that much longer if we'd kept going at that rate, but it was a big shift.

"I think the first year we tried to pretend that we could have that life still, and we can't - not being the parents that we want to be."

Knightley currently appears in The Nutcracker And The Four Realms, and will next star in period drama Colette, due for release in January.
