Recently the epilogue was asked about to Chris Sarandon and Ken Page at a panel! You can find it by searching 'Nightmare Before Christmas Q&A Panel 2022 MegaCon Orlando! Chris Sarandon and Ken Page' and it's under the YT channel 'Fast Times Vero'.
ANON! I can't thank you enough for telling me about this - I saw some Ken Page & Chris Sarandon events recently, but didn't look into them since I was away at the time. (The question is asked at 12:35)
I think this was a *really* funny question to ask to begin with - since Danny Elfman was the one who wrote the Epilogue. I didn't think they had an answer but the one they gave was PRICELESS. This is HILARIOUS ;;
"MAGIC."
I hope they weren't too uncomfortable with the question btw? Everyone seems to want to know how Jack and Sally had the skeleton kids. But it's probably not the most comfortable to answer in public, I imagine, so I hope they were fine with it? I think in another Interview somewhere Chris stated that he sees Jack as Asexual, so I wonder if that contributed for their answer? :)
