I was watching the ridiculous movie TROLL(1986) when I again witnessed the good witch in the apartment complex teaching Harry Potter about wizardry while her singing pet toadstool smiled sheepishly when it dawned on me: JK Rowling's fortunes can all be traced back to this funky sci-fry from the eighties. Check it out. The Sonny Bono cameo is worth it alone. Priceless, mindless entertainment. Harry Potter Sr.'s dance rampage is worth a few giggles as well. HAPPY FULL MOON.
