Red Head from Manhattan

Redhead from Manhattan is a 1943 comedy film directed by Lew Landers and written by Joseph Hoffman.[1] The film stars Lupe Vélez in one of her last screen appearances, Michael Duane, Tim Ryan, Gerald Mohr, Lillian Yarbo and Arthur Loft. The film was released on May 6, 1943, by Columbia Pictures.[2][3]

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, 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.
