The other night, I watched a film called Down to the Sea in Ships on TMC. Released in 1922, it is the oldest movie I recall ever recall seeing.
Previously, the oldest film I had seen was Charlie Chaplin's Gold Rush released in 1925. Right now I am in the process of viewing that film again, plus the 1942 re-edit of the film.
The oldest movie I saw in the theater was a recent restoration of the landmark 1927 film Metropolis. Lost footage was recently found and they added it for the restoration, although almost an hour of the original film is still missing and is probably lost forever.
What is the oldest film you have seen, both in the theater and on TV?
