I realized watching it that some of my absolute favorite movies have witches in them and lots of my favorite witches made the video clip. I don't do scary movies (The Birds, It and The Shining killed that for me), so all my witches are kinda not that scary. I watched Wizard of Oz so many times as a child that I burned through a VHS tape. This love was not carried over to Return to Oz however- the "wheelies" gave me some serious nightmares and that witch was a little more witchy. I loved the super creepy Witches with Angelica Huston. There is also a little known live action Hugga Bunch movie with a fabulous witch who had to eat magical apples to stay alive. Of course, Snow White and Sleeping Beauty feature some wonderful witches.
My all-time favorite witches are in Hocus Pocus. I LOVE Bette Midler and she is divine in this movie- as are SJP and Kathy Najimy. This was the movie that caused my then five year old brother to scream "I'm not a VIRGIN!" in the middle of a McDonald's playland. There is a fun part where Garry and Penny Marshall play an old married couple rather than brother and sister (sick!). There is dancing and singing and some really fabulous costumes.
I will end here with a quote from the hilarious Monty Python and the Holy Grail.
What is your favorite witchy movie?
Sir Bedevere: What makes you think she's a witch?
Peasant 3: Well, she turned me into a newt!
Sir Bedevere: A newt?
Peasant 3: [meekly after a long pause] ... I got better.
