Bloody hell! This is getting very silly when because a sailor shuts a round not oval w/t door the film gets rubbished.
I understand that films should be at least correct when its based on an event from history, but to get every action and object right too is pure madness!
So, what happens if the only submarine they could get only had round w/t doors.....do they say hell, lets not make the film because one or two people will notice it? Or do they say, well its still a good story?
