Alfred Hitchcock's Cameo Appearances

I just found this brilliant video via the always brilliant Roger Ebert. It's a collection of Alfred Hitchcock's cameo appearances in his movies. But it doesn't include all of Hitchcock's movies. Made by royvanderzwaan, according to the description, it says:

These are just the cameo appearances from the movies I own on DVD, missing are:
Easy Virtue (1927)
Blackmail (1929)
Foreign Correspondent (1940)
Suspicion (1941)
Spellbound (1945)
The Paradine Case (1947)
Under Capricorn (1949)
