Redhead from Manhattan

Lupe Vélez plays a dual role, twin sisters Rita and Elaine. After escaping a torpedoed ship, Rita shows up in Manhattan, where she takes the place of her Broadway-star twin sister Elaine (both parts played by Lupe Vélez), who's having problems with her marriage and needs to make a getaway. Neither Elaine's husband or Rita's saxophone-player boyfriend are aware of the switch.
