Warners' upcoming Ben Hur includes the silent version on blu.

Paramount released It's a Wonderful Life, and one of their releases of The Ten Commandments included the silent version on blu. That seems to be it from them.

Warner also released Clooney's Good Night and Good Luck.

Sony's also got:

There might be more from Sony, but those were the only three I could come up with off the top of my head.

Thanks for all of the help so far guys.

It's interesting to hear Ray Harryhausen--on at least one of the commentary tracks to this set--exclaim several times how impressed and delighted he is by the colorized versions included on the BDs. I guess innovative, revolutionary stop-motion animators are not conservatives when it comes to black and white photography.
