Who better than the estimable Barbara Payton to play the Bad Blonde in this Lippert release? Actually, the film was originally made in England by Hammer Productions, then released in Great Britain as The Flanagan Boy and This Woman is Trouble, but neither one of these titles had the box-office "sock" of Lippert's cognomen. The story finds the duplicitous Lorna Vecchi (Payton) wrapping boxer Johnny Flanagan (Tony Wright) around her little finger. It seems that Lorna is married to Johnny's manager, Giuseppe (Frederick Valk). But when her husband proves to be a nuisance, the "bad blonde" blackmails Johnny into murdering the man. Astonishingly, until the very, very end it looks like Lorna's going to get away with it! Bad Blonde was based on a novel by Max Catto.
