Here it is: the obvious, the shallow, the cosmetic reason for Keatonholism: his looks! I could write about soulful eyes, a perfectly imperfect nose, complementing mouth, chiseled bones, but in this case, pictures speak louder than words.
I rest my case.
On a not so shallow note, BK's features seemed specifically designed for performing. Large eyes, classic profile... The next time you watch an early Keaton film pay extra attention to his visage (there's a tough assignment). It stands out from everyone else on the screen.
This post concludes my little essay on why I continue to promote Buster Keaton. I could offer more, but for now, I'm sure you get the point. Thanks for reading.
