Nice little piece on Buster Keaton by Kenneth Turan over in the L.A. Times Calendar section.
You'll need to register and I'm going to suggest you do. They used to charge for this section so I never linked to articles over there, but it's now free and even if you don't live in Los Angeles, it's a pretty good site for entertainment-oriented articles.
Whenever I suggest registering for some free Internet site, a couple of people write me and say they won't do that because it will result in Spam and their mailbox will get clogged. I've never noticed that to result from signing up with the most prominent newspaper sites but if it worries you, get an alternate e-mail address for sign-ups. Get an account on Hotmail or Gmail or My Way or any of a hundred other sites that will let you sign up for an online mailbox. Use that address to sign-up and only check it when you have to.
