Back Street is a 1941 American drama film directed by Robert Stevenson and starring Charles Boyer, Margaret Sullavan and Richard Carlson.

Margaret Sullavan so much wanted Charles Boyer to play her leading man, that she relinquished top billing in order to persuade him to appear in this unsympathetic role.

One day she meets an extremely charming and handsome banker named Walter Louis Saxel, and they fall immediately into a strong attraction, which for her is real love.

The banker is now married with two children (Richard and Elizabeth) and is extremely successful in his career, but Ray and he still share the same strong attraction.

Ray goes back to Ohio and agrees to marry Curt, an attractive and good-hearted man who proposed to her many times in their youth.
