Though it wasn't part of the "I Love a Mystery" series (that wouldn't start at Columbia until the next year) "The Missing Juror" has the same writer, Charles "Blackie" O'Neal (Ryan O'Neal's father), and the same star, Jim Bannon. It also has the same breezy unconcern with plot credibility; like his script for the first "I Love a Mystery" movie, O'Neal's screenplay literally makes no sense, as well as being structured around one man impersonating another (I know I'm treading on the thin edge of "spoiler" here but IMDb's cast list actually gives the game away anyway) and supposedly not being recognized by two leads who know both people well. What saves this movie is George Macready's malevolent performance and, above all, Budd Boetticher's direction: Boetticher and cinematographer L. W. O'Connell take the film noir look to such extremes that some scenes are played out in almost pitch-black darkness and only flashes of light, along with the voices on the soundtrack, clue us in as to what's supposed to be going on. It's a pity Boetticher later specialized in Westerns and didn't make many more noirs — he was damned good at them!
