Green for Danger (1946)

After a man dies on the operating table of a British country hospital one of the nurses declares that it was murder and not only that, she knows who the murderer is! Later that night and before telling anyone who the killer is she is found dead. Enter the enigmatic Inspector Cockrill of Scotland Yard. The Inspector has five suspects, two doctors and three nurses but in order to find his murderer he must contend with rumours, back biting, a voice on the radio and a love triangle.

Sidney Gilliat, who wrote such classics as The Lady Vanishes and Millions Like Us, both directed and wrote the screenplay for this great British who-done-it. Trevor Howard, best known for Brief Encounter, and Leo Genn are the two suspect doctors fighting for the hand of the lovely Sally Gray. The excellent character actresses Megs Jenkins and Rosamund John are our other two nurses and possible murderers. Topping the table of great British actors in this movie however is Alastair Sim as Inspector Cockrill. Sim plays the Inspector as a gangly, slightly comedic but incredibly insightful, hiding in bushes, falling over gates but always on the case.

Leo Genn is often over-shadowed when talking about British actors of the mid 20th century. A little too English and a little too soft to make an impact as a male lead he gave some wonderful co-star performances, most notably as Starbuck in Moby Dick and Petronius in Quo Vadis.

This is a delightfully enjoyable film and well worth a look.
