Ok, near the beginning of said film, Private Joker murmurs something along the lines of: "Is that you John Wayne...is this me?", as a sort of p***take towards the drill instructor. Is this a joke or what, cos i just don't get it and have seen the film many many times.
I can only think it was because John Wayne won the war single handed in so many war films the Americans always seem to relate to this macho tough guy hero but in fact he did'nt actually serve in the army.
