Joan Collins has said that most of the actress over the age of 35 experiences ageism.

She said that though she got the role, at the end the producer said that had they known she was so old, they would have never cast her.
Collins added that the producer told her he wanted a 33 year old and it wasn't how she looked these days, it is how old she was and those days they can just look on Google.
