Twin Peaks

Steven Spielberg, who was a big fan of the show, was originally set to direct the first episode of the second season before David Lynch decided to direct it himself.

The weird vocal effects used during the "Black Lodge" sequences were achieved by having the actors learn their lines backwards. The result was then played backwards, meaning the lines came out forwards, but sounded bizarre and otherworldly.

There were plans to spin Sherilyn Fenn's character Audrey Horne off into her own series, that didn't come off. Apparently, Audrey inspired David Lynch for Naomi Watts's character in Mulholland Drive (2001), as Fenn said in an interview in 1997 about the Audrey Horne spin-off, "David was talking about 'Mulholland Drive', he talked about like 'Audrey goes to Hollywood'. She's driving along Mulholland in this convertible car... But it didn't end up happening."
