My go-to disc for White Zombie, which I just watched again tonight, is the 2013 Kino Lorber Classics blu-ray. I am always amazed at the picture quality they managed to restore from a film I remember seeing many years ago on TV and VHS that was barely visible, and audible, in many parts. The initial DVD from the Roan Group was a great improvement, but this Kino blu-ray is, IMHO, the runaway best transfer. What a great movie for Halloween time! Talk about atmosphere...
