Twin Peaks

Creators David Lynch and Mark Frost assigned no episode titles, only episode numbers. When the series aired in Germany, titles were assigned, which were then translated to English. The episodes are untitled on the DVD sets, but the titled episodes appear on the official Twin Peaks CBS website when streaming the episodes.

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."

Some scenes that explored the relationship between James Hurley (James Marshall) and his mother were filmed but finally never included in any episode.
