Cameos by the master of suspense

This past Sunday I got a reference question asking me about Alfred Hitchcock cameos and, in particular, where was Hitchcock's cameo in "North by Northwest." I managed to pull up a list from the Internet, of course.
For both the uninitiated and the experienced, I pulled this short two minute video of Hitchcock cameos. How many movies can you name? BTW, the answer to my reference question is included here.
