Genre blender of considerable worth. Lady on a Train is directed by Charles David and adapted to screenplay by Edmund Beloin and Robert O’Brien from a Leslie Charteris story. It stars Deanna Durbin, Ralph Bellamy, David Bruce, George Coulouris, Allen Jenkins, Dan Duryea and Edward Everett Horton. Music is by Miklos Rozsa and cinematography by Woody Bredell. Part murder mystery, part film noir, part comedy and part musical! And it’s a Christmas movie as well! Lady on a Train has a lot going on for sure. It’s a fun packed little movie that gives Durbin full licence to show her various talents…
