Washington, May 6 : It was a project that made her one of the top actresses in Hollywood, but Keira Knightley was ashamed of the 'Pirates of the Caribbean' franchise when she first signed the films - because they are based on a theme park ride.
The British actress made it big in Hollywood with the 2003 blockbuster, based on the famous attraction at Disneyland in California.
The film went on to span two highly successful sequels.
However, Knightley has confessed that she never imagined the movie was going to be so popular and felt ashamed to be associated with what she thought was going to be a very costly flop.
"Gosh, I was just a teenager and you can imagine it was the most embarrassing thing telling my mates I was about to be in a movie based on a Disney theme park ride," Contactmusic quoted her, as saying.
"I mean it was really f**king embarrassing and we all thought it was going to be total s**t anyway.
"But then suddenly I was kissing Johnny Depp and Orlando Bloom and bang, there you go, instant bloody stardom," she added.
