Colorizing movies is akin to correcting the anatomy of figures in expressionist paintings. Films are, mostly, made by artists. There are exceptions of course (Adam Sandler movies come to mine, but I suppose like debates that spring up about traditional fine art, there may be someone out there that will argue in favor of Mr. Sandler’s creative output). Some museums use velvet ropes to keep people from even getting close to works of art and this is understood by everyone to be a good policy; yet we accept the molestation of films by third parties? Why? Obviously films are products made for mass consumption, but that shouldn’t give anyone the right to alter an artist’s original intent.
Black and white cinematography is also beautiful to look at. I recall reading an interview with Billy Wilder in which he explained how difficult lighting for black and white film could be. All that so the fumbling hands of some network editor can trample on not only the director’s vision, but that of his Director of Photography as well? And of course the result is never aesthetically pleasing. Print out a black and white photograph and color over it with crayons. Does it look better or worse than the original photo?
