Gunga Din (1939)
Based loosely on the poem by Rudyard Kipling, this takes place in British India during the Thuggee uprising. Three fun loving sergeants are doing fine until one of them wants to get married and leave the service. The other two trick him into a final mission where they end up confronting the entire cult by themselves as the British Army is entering a trap. This is of the "War is fun" school of movie making. It has the flavour of watching Notre Dame play an inferior high school team.
