Why black + white?
I quite like the film just as it is, but wondered (while watching the "Making of" documentary) what the reasoning was for choosing to film it in black and white, since even in the 50's color film was the norm. Was it to save money? To give it a more "documentary" feel? To re-create the ambiance of the time? Filming in color would have made it difficult to incorporate those shots from the launching of the Queen Elizabeth et al.
I was surprised that this was not mentioned and wondered if anyone knows the reasoning behind it?
