In the '50s, there were a lot of British noirs made with American stars such as Dane Clark, Dennis O'Keefe, Cesar Romero, and others. These noirs were usually atmospheric and fun to watch.
"The Shadow Man" is from 1953 and stars Romero, along with Kay Kendall. Romero is Luigi, who owns a pin-table saloon. Apparently this is some sort of a casino with pinball machines. Anyway, the cops are usually watching it because some of the patrons are not of the highest quality.
Luigi meets and falls for Barbara (Kay Kendall) whose husband is a gambler and not much of a husband. She agrees to go away with Luigi, but when Luigi's ex-girlfriend Angele (Simone Silva) winds up dead in Luigi's apartment, Luigi has to ask help from his employee, Limpy (Victor Maddern) for help, and then hide out and try to figure out who murdered her.
There's nothing very special about this, except that I have always believed Cesar Romero was very underrated as an actor. He's marvelous here, very handsome with a great presence, using just a touch of his accent. His saloon is crowded, chaotic, nothing fancy, and has a wonderfully '50s atmosphere. Kay Kendall, his costar, would go on to big fame before her early, tragic death (recounted in the play "In Praise of Love," originally starring her then-husband, Rex Harrison).
Nothing exceptional except Romero and Kendall, but they make it worth seeing.
