Lady on a Train(1945). Comedy, shot in film noir style. Cast: Deanna Durbin, was directed by Durbin's future third husband Charles David. The film's music score was by Miklós Rózsa. Durbin sings, "Silent Night" and "Night and Day." The comedy, musical and film noir seems to be a spoof on Cornell Woolrich mystery stories. Cowboy star Lash La Rue, plays a waiter at the Circus Club.
Nikki Collins, is a witness to a murder while traveling by train. Nikki goes to the police, who believes that her story is a figment of her imagination. Nikki, then goes looking for mystery writer Wayne Morgan, to help her solve the case.
Lady on a Train(1945). reminds me a little of a Agatha Christie movie. One of my favorite scenes was in the night club/dressing room.
