Ghostbusters in black and white is phenomenally creepy. Seriously, if you get the chance, give this one a go.

I also really dig two-disc special edition of The Mist, which included Darabont's original idea of showing the film in black and white. The producers shot that idea down, saying audiences in the 21st century wouldn't go see a film that wasn't in color. While they were probably right, it's still a gorgeous way to experience the movie, and it gives it the feeling of an extra long episode of The Twilight Zone or The Outer Limits. Highly recommended. :)
