Producer Richard Conte comes to Hollywood to make his next picture. While he's figuring out a subject, he rents an old studio. The guard tells him about a director murdered at the dawn of sound, still unsolved. Conte decides that will make a terrific picture. High school friend and now Hollywood agent Jim Backus hates the idea, as does Conte's partner Fred Clark. Julia Adams, the daughter of a movie star with whom the dead man was linked, asks him to drop it. Even police detective Richard Egan comes by to quiz Conte and tell him it's a terrible idea. conte persists, even hiring the dead director's washed-up screenwriter, Henry Hull. Then there is another murder...
It's a canny, nostalgic movie directed by William Castle, who knows how to evoke old Hollywood without getting trapped in antiques. The studio that Conte rents is Chaplin's studio, and there cameos for a Betty Blythe, a Francis X. Bushman, and William Farnum. The mystery, although far from the William Desmond Taylor murder that inspired it, is nicely constructed, with some decent red herrings. It's a fine example of the unassuming picture that does everything you so right that that it becomes a minor masterpiece.
