DANGER ON THE AIR (1938) is a delight for fans of B movie mysteries. The setting is a radio station and the pace is quick and full of fun characters. The leads, Nan Grey and Donald Woods, are a well-matched set of amateur sleuths. Their objective is to solve the murder of a lecherous, tight-fisted sponsor. They certainly have enough suspects among the staff and rivals in the media industry. It is great fun seeing a young Lee J. Cobb portray the elderly janitor. An entertaining bonus is a baby-faced Peter Lind Hayes doing bang on impersonations of famous radio stars of the time. Get that popcorn ready and turn the lights down low.
