I believe the black and white brought the contrast to a pop. I mean color would have muted the lines.
I've loved musicals for as long as I can remember. My first was Carousel. When I was in sixth grade there was a morning movie show. I was late to school often. That's where I first saw it. I can't say what my favorite is. To many. When my **** husband and I were dating in 74 I took him to see Cabaret and he really liked it. That was a plus for him. His favorite is Fidler on the Roof. Right now I'm watching Victor/Victoria on AMC again. Plus I have it on my DVR.
