Piccadilly Incident (1946)

Very genteel British wartime romance in which Michael Wilding eventually remarries after believing his wife of only three days (Anna Neagle, looking incredibly good for 42) has died at sea, only for her to turn up alive and well. It's all very British - exaggerated politeness, stiff upper lips, chirpy working classes, etc - which makes the outlandish plot seem even more far-fetched than it probably is. Director Herbert Wilcox seemed to struggle to fit all that plot into the 103 minute running time, as some key events are glossed over.
