From Roger Ebert's Movie Website
Bob Sassone: I've read with great interest your comments concerning the benefits of black and white films, and I couldn't agree more. In fact, I have actually taken several videos, turned the color off on my TV and watched them! It's amazing how many poor or average movies are improved somehow by having them in black and white. It gives the film more depth, more surrealism—an almost film noir edge and mystery. This isn't to say that the latest Pauly Shore movie is improved, of course, but you know what I mean. What do you think of my practice?
Roger Ebert: Although I am opposed to colorizing black and white movies, I must confess that I have occasionally de-colorized color movies, and find that they frequently play better that way, especially if the color is either garish or faded. Recently I found that "The Barefoot Contessa" made the transition especially well.
