Quoted from Yoko2una:Honorable mention - the one where they redid that French film.
Occurence at Owl Creek Bridge? They didn't do anything other than slightly edit that film to fit the time slot. Pretty remarkable we never noticed the dialogue change!
For me:
"Nick of Time" (Shatner in the diner),
"time Enough at Last" (Burgess Meredith at the end of the world at the library),
"The Invaders" (space aliens attack Agnes Moorehead in a rustic house)
"Little Girl Lost" (basically the 2nd half of Poltergeist, amazingly creepy episode even if it's kind of clunky)
"Death Ship" (astronauts find a crashed, exact copy of their ship, with themselves inside - same ship as The Invaders! Same ship as Forbidden Planet. Also, my TZ topper)
Also, "Steel" is pretty good - I kind of like the episode better than that movie with Hugh Jackman. Basically all the TZ episodes come out better than the later films based on them.
