Indicator’s latest box set of noir B-movies is devoted to Columbia’s series adapted from a popular radio show in which the mysterious Whistler observes and comments on the fates of various characters whose lives go off the rails. In the first seven movies, character actor Richard Dix suffers a variety of situations, sometimes as victim, sometimes as the perpetrator of murder; after the actor’s death, the studio made one more film, replacing him with the bland Michael Duane, before retiring the Whistler for good.
