This is a clip from silent film comedian Harold Lloyd's most famous film, Safety Last:
It should be noted that the only special effects used were the fact that the building facade was on top of a building, to give the illusion he was on the side of the building. But, other than that, Lloyd did his own stunts, and with one good hand- the other was blown off in an explosion earlier in his career.
Today, he is almost wholly forgotten, but only Chaplin was a bigger silent comedy star. Lloyd was even bigger than Buster Keaton. I first saw his shorts, as a boy, on the old Joe Franklin tv show on WOR in New York. You go, Harold.
