Knights of Sidonia manga creator Tsutomu Nihei and Knights of Sidonia anime co-director Hiroyuki Seshita discussed the possibility of a third season of the Knights of Sidonia television anime series at the "Spotlight on Tsutomu Nihei " panel at Comic Con International in San Diego on Saturday. When asked if Knights of Sidonia was getting a third season or if it would get movie adaptations, Nihei said, "I'm also waiting for Sidonia 3! But I'm not the one who is making it or getting funding for it. So it's up to this guy" and pointed at Seshita.

Seshita then said, "I don't have time to do it right now, but I'll definitely get to it. So if you watch and support Knights of Sidonia and do the same for Blame! , that will increase our chances of that coming true."

The Blame! film, which will be a Netflix Original, will premiere in 2017.

The first 12-episode season of Knights of Sidonia premiered in Japan in April 2014. The second 12-episode season, titled Knights of Sidonia: Battle for Planet Nine , premiered in April 2015. Netflix streamed both seasons of the anime adaptation after they aired in Japan. Sentai Filmworks released the first season on Blu-ray Disc and DVD in June 2015, and will release the second season on Blu-ray Disc and DVD on November 29.

A theatrical film compiling all 12 episodes of the first season with new sequences and redone sound effects opened in Japan in March 2015, and Sentai Filmworks ' release of the second season will include the film.

Vertical Comics released all 15 volumes of the original Knights of Sidonia manga in North America.
