This film is from the safe driving genre (some fun educational videos), but it has many extras in it that make it a cut above average. Famous actor Jimmy Stewart narrates, introducing four unrelated people who are going to be filmed for one day. Stewart informs the audience that by the end one of them will die in a car accident. They each drive different cars or have different car safety features, any of which could lead to bad car accidents: one drives a hotrod, one has faulty brakes. The suspense is heightened effectively by knowing ahead of time that only one group will die, and guessing at which one. A fine example of 1940's melodrama, And Then There Were Four explores safe driving topics as well as the risk factors of driving. Of the many Jimmy Stewart narrations, this film about unsafe car dangers is highly entertaining.
