Elizabeth Taylor in Who's Afraid of Virginia Woolf?.  Taylor changed the role of Hollywood women in film as a result of this extraordinary performance.  This was acting that opened it up to artists like Streep. Taylor was  paid top dollar before and during the time this movie was made.  It helped that her beauty was sublime.  Before De Niro altering his appearance in Raging Bull, there was Taylor playing, Martha.   She successfully pulled off acting  as a woman who took no prisoners, and looking much older than her actual age.  If there was one award for best actor for female or male, Taylor would have won.  I know there have been many great actors but Taylor set the standard for acerbic wit no woman or man has matched.

All that being said, Women are equal in making movies great, and deserving of complete equality in income and opportunity for great roles.  I thought that this went without saying.  If not, the way to end this foolish argument is via class action.
