Tonight at 8 PM on TCM they will be showing the remastered German Expressionist SF classic Metropolis. This will be the first time in over 80 years that the full-length version will be shown, including 25 minutes once thought lost forever until discovered in Argentina a few years back.
This is literally going to be cinematic history, and if you've got TCM you'll get to see it for free. I hope you can; I know I'm going to.
Best all!
