Wow, another great idea Dan! I can definitely see that; very provocative questions.
I think I saw the very beginning of that UPN sequel and was quite impressed that they not only got Bill Mumy (Anthony) back but also the actress who played his mom!

It was amazing how both actors were just able to pick up where they left off regarding two characters they hadn’t played in thirty years or so. (Especially Mumy.)
“It’s a Good Life” is hands down one of the all-time best TZ eps ever!

(In my opinion.). It’s almost sort of a mini-movie or maybe even a one-act play. The acting is terrific all-around, but Bill Mumy, even though he was only six or so, should really be given more recognition of how convincingly terrifying he made Anthony (the kid in The Movie was fine, but he doesn’t hold a candle to Mumy).
Seriously, when it comes to on-screen child psychopaths, he is undeniably up there with the stars of The Bad Seed, The Good Son, and Orphan!
CBS clip from said ep...(but they cut off the very last minute: “Tomorrow’s gonna be a real good day!” Oh well.

You can’t just have your characters announce how they feel! That makes me feel angry!
