The basis of the plot is a group of ex-Army officers rob a bank with a very military and effective plan. It was one of the first English films to have all the elements of the successful 1950sU.S. heist films, although with a distinctly English tinge.
The film was the most successful British film of 1960.
Initially it seems like an odd decision to focus on these three, but one of the League's many joys was the way they gave depth and shape to all their characters as the series progressed.
This is a film that works within its own parameters, necessarily ditching some of the show's fler elements and instead humanising previously one-note characters, a process that is made possible by the not inconsiderable acting talent of the central trio, especially Gatiss as the repulsive but commanding Briss.
The League have envisaged this as a stand alone film and, while it has no real narrative connection with its TV counterpart, it's hard to imagine what you'd make of it without prior knowledge of the characters and their world.
When films began to tell stories, instead of just record brief events, exhibitors sometimes provided a commentator to narrate the action, but this became unnecessary with the development of printed intertitles containing the actors' dialogue and other written, descriptive material as part of the visual experience.
A film score is the background music in a film, generally specially written for the film and often used to heighten emotions provoked by the imagery on the screen or by the dialogue.
