Overview
Tanks a Million is a 1941 American film directed by Fred Guiol. It was the first of Hal Roach's Streamliners, short films under an hour designed for the lower half of a double feature. The two leading characters, whiz-kid sergeant Doubleday (played by William Tracy) and his rival Sergeant Ames (Joe Sawyer), would go on to feature in seven more films, though the series has no overall title.
Despite the title and military setting, no tanks are seen in the film.
Plot summary
Dorian Doubleday, "Dodo" to his friends, works as a clerk at a railway station but he has the ability of photographic memory. When he is drafted in the Army, he memorizes all the manuals for Army procedure immediately before starting his service.
Because of his extensive knowledge of procedure, he is quickly known as a know-it-all at the basic training in Camp Carver. His drill sergeant, Sergeant Ames, disapproves of him from the start, but the officers above him are quite impressed with the new recruit due to his memorisation and word perfect recital of Army Regulations.
