Earthbound (1940)

I quite enjoyed this daft little crime caper. "Nick" (Warner Baxter) has been shot, stone dead as a dodo - and his pal "Jeff" (Henry Wilcoxon) looks set to swing for it. Thing is, he didn't do it. We know he didn't - he is just covering for someone, but whom? Well the spirit of "Nick" is determined to try and help, even if nobody can actually see or hear him - except "Whimser" (Charley Grapewin) who might have some clues that will turn him into the original "influencer"! Using some simple and effective visual effects, Irving Pichel now takes us on what is, admittedly, a rather procedural cat chases mouse affair using his widow "Ellen" (Andrea Leeds) to investigate and deliver the fairly obvious culprit before it's fry-day for "Jeff". It's only an hour and moves along quite amiably without remotely taxing your little grey cells.
