Excellent movie, but I wouldn't call it unknown.
Beat me to it! I was too busy relating quotes from "The Wind and the Lion".
Any movie with BOTH Connery and Caine AND the story by Kipling is bound to be great!
True but “most people” haven’t seen it as far as I can tell.
Now, Hot Cars (1956) with 20+ minutes of Joi Lansing-
but I digress...
Some great choices on this thread, and a lot I hope are great choices..
