Buster Keaton

[rhialto]

Many movies by Buster Keaton are in the public domain now. One that I like very much is One Week. It is about a newlywed couple which receives a wedding gift from an uncle: a plot of land and a "portable house", that one can easily assemble in a week. Oh, and there is an onrushing train as well.
Archive.org has many more of his films too.
