The Green Cockatoo(1937)

This has some good ingredients to make a jolly, if not exactly, menacing murder story - but it's all just way too fluffy and talky. The doey-eyed Rene Ray is "Eileen" who arrives into London very late one night. At the station, she encounters "Dave" (Robert Newton) who offers to show her an hotel where she might pass the night. What she doesn't know, is that her good Samaritan has fallen foul of some crooks and a station fracas ensues and he is mortally injured. Before he croaks, he gives her a message to give to his brother "Jim" (John Mills) in the eponymous nightclub. She meets the brother, but a rather unlikely series of mishaps befall the pair as they are being sought by the police and the hoodlums. Aside from some singing and dancing that one wouldn't normally attribute to John Mills, the thing is entirely procedural with little by way suspense or peril; and saving a rather curious performance from Frank Atkinson as the butler "Protheroe" would be instantly forgettable.
