A cult film I've really enjoyed since I saw it way back when as a midnight show - at the Waverly Theatre in Greenwich Village in the early 1980s - is Richard Elfmann's Forbidden Zone (1980).
Thirty-four years later(!) Elfman is using Crowdfunding to raise money to film a sequel. And yesm brother Danny Elfman is involved. I sent in a few bucks - I wonder if lightning can strike twice, three decades apart? Animator Jeaux Janovsky created this promo (below) to help the cause - though they've apparently already reached their goal on Indiegogo.
