Ted Sarandos, Netflix’s co-ceo, revealed that David Lynch, the renowned filmmaker known for his surreal and innovative work, was secretly working on a limited series for the streaming service before he passed away at the age of 78. The project, which was seen as exciting and unclear, was put on hold because of the Covid-19 outbreak and Lynch’s worsening health.

Sarandos posted a moving tribute on Instagram after Lynch passed away on Thursday. Sarandos called the series a typical Lynch project, full of “mystery and risks.” He mentioned that Netflix was excited about the idea when Lynch presented it.

The project is thought to be linked to a suspected series called “Wisteria” or “Unrecorded Night,” but specific details are still unclear. Lynch had intended to write and direct 13 episodes, working with Peter Deming, his cinematographer from Lost Highway and Mulholland Drive, according to a 2020 listing in the trade magazine Production Weekly.
