It’s an annual tradition at Syfy, the 4th of July marathon of Twilight Zone episodes, and it begins at midnight ET tonight, so get ready for the earliest batch, which in these overnight hours includes Carol Burnett and Jesse White in a Rod Serling-written 1962 episode, “Cavender is Coming.” Of special interest when watching this episode: Burnett told me she had a major crush on Serling at the time, though nothing happened and he was, at the time, happily married.
