All About Eve (1950)

At an awards dinner, Eve Harrington (Anne Baxter) — the newest and brightest star on Broadway — is being presented the Sarah Siddons Award for her breakout performance as Cora in Footsteps on the Ceiling. Theatre critic Addison DeWitt (George Sanders) observes the proceedings and, in a sardonic voiceover, recalls how Eve's star rose as quickly as it did.

The film flashes back a year. Margo Channing (Bette Davis) is one of the biggest stars on Broadway, but despite her success she is bemoaning her age, having just turned forty and knowing what that will mean for her career. After a performance one night, Margo's close friend Karen Richards (Celeste Holm), wife of the play's author Lloyd Richards (Hugh Marlowe), meets besotted fan Eve Harrington in the cold alley outside the stage door. Recognizing her from having passed her many times in the alley (as Eve claims to have seen every performance of Margo's current play, Aged in Wood), Karen takes her backstage to meet Margo. Eve tells the group gathered in Margo's dressing room — Karen and Lloyd, Margo's boyfriend Bill Sampson (Gary Merrill), a director who is eight years her junior, and Margo's maid Birdie (Thelma Ritter) — that she followed Margo's last theatrical tour to New York after seeing her in a play in San Francisco. She tells a moving and involving story of a difficult life, including losing her young husband in the recent war. She is becomingly humble and flattering in her idolization of Margo. In response, Margo quickly befriends Eve, moves her into her home, and takes her on as her assistant, leaving Birdie, who instinctively dislikes Eve, feeling put out.
