Keaton's last film was a short film promoting the CPR or the CNR I forget which Canadian railway. I've seen it and it is pretty good. I think it was in the 60's. I saw an interview with his wife about him and the making of that short. There was a scene that he wanted to do standing atop a railway car as it was travelling over a bridge and he would be trying to read a map that kept getting blown into his face. The producers were aghast and wouldn't let him do it because it was so dangerous. I think they had him sitting in one of those little track cars that you pump instead and had the map keep blowing in his face. It's been a long time since I've seen it so I may be off a little. His wife said that he didn't drink anymore but always had a beer. So much for the AA propaganda.

If you look up the Keaton box that Kino put out a couple years back, there's an extra DVD called Keaton Plus. It contains a lot of the commercials he did.

Keaton and Chaplin were two great comedians of the silent era or any era for that matter and it's silly to either be in one camp or another. One may appeal to you more than the other, but that has to do with your personal taste. It's like arguing what's better, Sirloin or T bone? Well Sirloin is better, but it's a silly argument.

On the other hand....he actually expresses so much with his "pokerface" and is amazingly expressive.
