I would add The Addams Family (1991) and Addams Family Values (1993) to your Funny and Spooky list. I’ll also second the The Fog (1981) suggestion.

True, but I think maybe you missed this being about additive and subtractive color mixing.

Interesting idea, I’ll have to try it sometime.

Otherwise broccoli stems are not too versatile.

I just throw them into whatever I’m making that uses the florets (peeled and chopped, ofc), and it’s always been fine. Alternatively, try shredding/julienning them (again, peeling first) and throwing them into a fresh batch of coleslaw.
