In short: Directed by Roy William Neill and starring Basil Rathbone, Terror by Night is a quintessential 1946 detective thriller. While critics at the time dismissed its plot as unoriginal, the film remains a beloved example of the genre, currently available for free viewing as part of the public domain.

Released in 1946, Terror by Night features the iconic pairing of Basil Rathbone as Sherlock Holmes and Nigel Bruce as Dr. Watson. The film follows a high-stakes investigation aboard a train, where the famous Star of Rhodesia diamond is stolen shortly after the murder of Roland Carstairs. Despite the film's reliance on established tropes, it masterfully utilizes the confined, fast-moving setting of a train to create a sense of urgency and scope that critics of the era noted helped elevate its otherwise wordy narrative.

The plot is largely original, though it incorporates minor elements from several Arthur Conan Doyle stories, including The Adventure of the Blue Carbuncle and The Sign of Four. The mystery deepens as Holmes encounters a suspicious coffin, a poisoned dart, and the notorious jewel thief Colonel Sebastian Moran, portrayed by Alan Mowbray. The film’s climax involves a complex ruse where Holmes uses an imitation diamond to outwit the criminals, eventually exposing an impostor inspector and securing the real gem during a chaotic scuffle.

Contemporary reception was mixed. The Monthly Film Bulletin described the performances as customary and the plot as uninspired, placing it firmly within the ranks of standard detective fare. Conversely, Kine Weekly praised the film’s neat climax and the illusion of pace created by the train setting. Interestingly, the publication questioned the British Censor's decision to grant the film an 'A' certificate, arguing that since children were permitted to read the original Sherlock Holmes adventures, they should be equally free to watch them on screen.

Today, the film is notable for being one of four entries in the Rathbone-Bruce series that has entered the public domain. This status has made it widely accessible to modern audiences, who can view or download the feature through the Internet Archive. It stands as a testament to the enduring popularity of the Holmes character and the specific cinematic style of mid-1940s British crime dramas.
