Film lovers are mostly aware of the large number of films that are lost - last copies destroyed, sometimes deliberately, or all copies on fragile stock that could not be duplicated. Occasionally a surviving print is found, mislabeled in old film vaults, or in bizarre situations like those found frozen in permafrost in Alaska.
So it’s possible that almost any “lost” film could turn up. If it was only one more in your lifetime, what (preferably major) lost film would you pay $100 for a seat at the first-night showing?
I don’t have a good reason for it, but *Convention City *would probably be mine, now that a 99% complete *Metropolis *has been assembled. (Oh, and the first IMDb trivia item for this film on cracks me up.)
