The Bibí Andersen who used to be a man has been in a few selected Almodóvar, and even more Almodóvar rip-offs.  The Bibi Andersson who deserves inclusion here starred in many of Bergman's films.  One actress I'm surprised hasn't been mentioned is Liv Ullman.  As for American actresses working today, Meryl Streep.  And I second (though she's been mentioned several times) the inclusion of Isabelle Huppert.
