I’ve heard Alicia Silverstone both as Samantha in BEWITCHED and Jeannie in I DREAM OF, with Barbara Eden as her Mom.
I’d love to see a TWIN PEAKS film finale tying up the show’s loose ends but that will never happen.
GILLIGAN’S ISLAND has been discussed for years- including by Sherwood Schwartz, its creator. I like Goodman as the Skipper. Jim Carrey’s too old for Gilligan. Not sure who I’d go with. Edward Herrimann as Mr Howell in a natch. and for a bit of surreallism- Janeane Garafalo as MaryAnn (I’d have also had her as Velma in ScoobyDoo). Anthony Stewart Head as the Professor (which makes me think of a Buffy paraody that has Willow as MaryAnn, Anya as Ginger or vice versa, Xander as Gilligan)
