All About Eve (1950)
From AFI’s 100 Years: 100 movie quotes - Part. 1
I didn’t have to worry about my looks. If you have to be concerned about your appearance, acting goes out of the window. Margo Channing was past forty. So was I. I was supposed to look the way I did. I see no reason why a woman of forty should be embarassed by trying to look as well as she can. It’s a cliché — and I think Hollywood established it — when a woman at forty is supposed to be a character. It’s not true. (…) People get that idea that actresses my age are dying to play younger women. The fact is we die everytime we play them.
