1 revealing mistake in The New Neighbors Meet the Addams Family
Starring: John Astin, Carolyn Jones, Jackie Coogan, Ted Cassidy
Morticia and the Psychiatrist - S1-E2
Continuity mistake: When Morticia is watching Gomez and the trains, at the second of the collision and explosion, it's a re-use of the shot when Mr. Hilliard is there, as in just a split second, you can see him, then there's Morticia again.
Grandmama Addams: Fester, You're not cheating.
Uncle Fester: Sorry.
Trivia: Originally, Lurch was supposed to remain mute for the entire show. In the pilot, when the bell is first rung to summon Lurch, Ted Cassidy ad-libbed the line, "You rang?" This caused everybody to burst into laughter and from then on Lurch would talk.
Question: How was effect of the light bulb that lit up whenever Fester put it in his mouth achieved?
Answer: Basically from what I understand, they stuck the innards of a small flashlight into the base of the bulb and put a little switch on it. When he put it in his mouth and bit down, his teeth would hit the switch, which would turn on the flashlight and made the bulb light up.
