THE TWLIGHT ZONE MARATHON
Syfy, 12:00 a.m. ET
The “every episode in sequence” mega-marathon of Rod Serling’s iconic The Twilight Zone continues, all day and all night. Part of the fun, in this case, comes from catching the less familiar episodes, and watching, even after all this time, a Zone that, though not new, is new to you. But there also are the joys of revisiting the classic standbys, which, today, would include “To Serve Man” at 5 p.m. ET and “The Dummy,” starring Cliff Robertson (pictured) at 9:30 p.m. ET.
