Buster Keaton on “The Twilight Zone”

Looking back with the benefit of a half-century’s worth of media history, the original run of The Twilight Zone seems like it was a breeding ground for soon-to-be-famous stars: it featured early-career appearances from actors like Robert Duvall, William Shatner, Martin Landau, and many more. But The Twilight Zone also provided a home for well-established film actors to do something a little different than their typical bread-and-butter movie roles. That’s certainly the case for a Season 3 episode called “Once Upon a Time,” which aired in 1961 and starred one of silent film’s greatest stars: Buster Keaton.
