WARNING: This article contains spoilers for Dark season 3 that may influence your enjoyment in discovering the plotlines. Read at your own risk.

Dark season 3 is in the middle of filming in Germany. The sci-fi mystery drama series was renewed by the end of May 2019 with production following after four weeks.

Co-Creator Baran bo Odar confirmed, on his Instagram, that work in Dark season 3 began in July. He also reiterated that this will be the last installment of the series since the show has always been planned out as a three-season offering.

No official release date for Dark season 3 has been released so far, but Baran bo Odar did say the show is expected in 2020. The first season Dark on Netflix was out in December 2017. Dark season 2, on the other hand, was released on the streaming platform in June 2019.

According to Screen RantDark season 3's principal photography could be completed by fall 2019. Give or take a few more months of post-production; the new installment could be ready by summer 2020. 

Meanwhile, despite planning out Dark as a three-series run from the beginning co-creator Jantje Friese told IndieWire that they still had challenges to put the story together and give it a satisfactory close. Figuring out how to get to the ending that they had in mind presented new challenges, especially with the show's tricky timeline.

Friese, however, confirmed that Dark season 3 would feature a grown-up Ulrich more than previous seasons. She also said that Claudia and Egon, as well as Martha and Jonas, will each have their moments. 

While fans might expect the mysteries surrounding Dark season 3 will be answered in the final chapter, the head writer revealed that there would be some things left unsolved. 

"Sometimes it's funnier [that way]," Friese teased. "I'm still not sure about the percentage, but it's probably 10 percent [of the mysteries] we are not going to answer just for the fun of it, but they will be smaller." 

Friese and Bo Odar have met during film school and collaborated on many projects together. In 2014, Netflix approached the duo for a different German-language show but instead pitched the story of Dark.

They didn't expect it would be a hit outside of Germany even if they approached the show's treatment for the global market that Netflix has been trying to build. Variety reported that 90 percent of viewers of Dark come from other territories.
