Hastings Mystery Theater is a Michigan-based vintage cinema program hosted by Randall Schaefer (the "Mystery Master"), who provides historical trivia and context for classic whodunnits and film noir on YouTube

One of the show's featured films is the 1946 British classic "Green for Danger." Directed by Sidney Gilliat, this World War II-era thriller follows the eccentric Inspector Cockrill (played by Alastair Sim) as he investigates a string of murders at a rural emergency hospital, beginning with a postman who dies mysteriously on the operating table. The film is highly celebrated for its clever blend of dark wartime tension and witty suspense.

The Stranger (1946), a relentless United Nations war crimes investigator named Mr. Wilson (Edward G. Robinson) tracks an escaped Nazi mastermind, Franz Kindler (Orson Welles), to a sleepy Connecticut town where the fugitive has reinvented himself as a respected prep school professor named Charles Rankin. To solidify his new identity and secure a perfect cover, Kindler marries Mary Longstreet (Loretta Young), the unsuspecting daughter of a Supreme Court Justice. When a former associate arrives begging for spiritual redemption, Kindler brutally murders him to protect his secret, triggering an intense psychological cat-and-mouse game with the suspicious Wilson. As the walls close in and his frantic paranoia escalates, Kindler plots to eliminate his increasingly doubtful wife, culminating in a legendary, deadly showdown atop the town's historic clock tower.

"The Mad Scientist Caper" (Episode 109), a famous but highly eccentric and slightly unhinged inventor named Raymond Fox hires private eye Sam Spade. Fox claims that a powerful corporate executive, Alfred Grierson of Grierson Enterprises, has stolen his groundbreaking secret formula for "Pentron"—a revolutionary new plastic that is stronger than lead but lighter than aluminum.
