Postmark for Danger was filmed in England, where it was released as Portrait of Alison. Terry Moore stars as an American actress who becomes the unwitting dupe in a diamond-smuggling schemes. Ingredients essential to the action are a beautiful strangulation victim (Josephine Green), an unusual charm bracelet, a curiously labelled bottle of chianti, and a hastily sketched drawing on the back of a postcard. The screenplay, by cinematographer Guy Green (who also directed), was adapted from a popular British TV serial. Released stateside by RKO Radio, Postmark for Danger was produced by Tony Owen, the husband of actress Donna Reed.
