Roger Ebert recently picked Buster Keaton's The General as the best silent movie ever made. City Lights notwithstanding, I agree.
As for why it shows up here in 1926, despite its 1927 American release, it premiered overseas in '26, and with Fritz Lang's Metropolis on the horizon, that's good enough for me.
