Bette Davis delivered the iconic line, "Fasten your seatbelts. It's going to be a bumpy night," in the classic film All About Eve (1950). Davis portrayed Margo Channing, a Broadway star whose life becomes disrupted when a scheming young actress named Eve Harrington (played by Anne Baxter) enters her world. The quote has since become a popular phrase used to express anticipation or warning of a difficult or chaotic situation.
