Keira Knightley feared being fired

She told the New York Post newspaper's Page Six column: "I remember going to Hollywood .?.?. I had only packed a small bag because I was convinced they were going to fire me."

The 'Begin Again' star also admitted she struggled to adapt to life after making a name for herself in the franchise and found the harsh criticisms of her performances hard to take as a teenager.

She explained: "Being a teenager that's come out of sort of big blockbuster films, there was a lot of criticism.

"People saying, 'She's s**t, she can't act, she can't do it. What's the point? She's pouty, she's thin.'

"Being a teenager, you do read it all .?.?. you go, 'Oh, my God, I'm that awful.'"

Despite receiving worldwide recognition for her performance in the movies opposite Johnny Depp and Orlando Bloom, Keira confessed she isn't keen on reprising her character for the eagerly-awaited fifth film 'Pirates of the Caribbean: Dead Men Tell No Tales'.

When asked if she would consider returning to the role, she said: "No, I don't think so.

"It was an amazing point in my life, but it was a good five-year chunk. It was incredible, but I can't really imagine going back to it."
