Vivien Leigh as Cynthia in Fire Over England (1937). It is the first film where Vivian Leigh and Laurence Olivier appear together, and Leigh's performance convinced David Selznick to cast her as Scarlett O'Hara in Gone With the Wind (1939).
In Buster’s 1935 short film The E-Flat Man, Buster couldn’t resist making a parody of this very famous scene from the previous years hit movie, It Happened One Night, starring Clarke Gable and Claudette Colbert.
