Jamie Lee Curtis believes there is a "conspiracy" in Hollywood to make actresses have cosmetic surgery.

The 51-year-old star thinks it's wrong that so many older actresses feel under pressure to change their appearance to try and keep working in the movie business.

Resisting plastic surgery pressure ... Jamie Lee Curtis and Sigourney Weaver.

Curtis said: "Everybody is saying that to get jobs you have to dye your hair and get injectables. It's a conspiracy, a complete catastrophe, a surgical industrial complex. Somehow we are being fed this belief that to continue on we have to do this. Yet people are being disfigured. It's shocking what people are doing to their faces."

The actress is adamant she will never go under the knife and plans to quit acting in the next few years before she stops being considered for roles.
