After the war, British films began avoiding the heiresses and lordships that had dominated the drama field and began pursuing "realism" -- which often was just as artificial as the earlier white-telephone pictures. John McCallum plays Tommy Swann, a product of the working class who tries to better himself by becoming a criminal. Escaping from prison, Swann hides out in the East London home of his former mistress Rose (Googie Withers), who has since married George Sandigate (Edward Chapman). The film is told from Swann's point-of-view, and a dismal view that is. Nor does Rose seem any happier with her drab lot in life. Swann's return does nothing but further their misery, tearing Rose' family apart and sending Swann back into the arms of the law. Considered a tension-laden slice of life in 1949, It Always Rains on Sunday seems a bit contrived today, though it does full justice to the Arthur La Bern novel on which it is based -- especially when the film leaves the environs of the house and zeroes in on its colorful roster of bit actors.
