|“||God was supposed to be gone. (...) We were free. (...) How the hell are we supposed to fight God?||”|
Supernatural was renewed for a fifteenth season by The CW on January 31, 2019. The season will consist of 20 episodes and will air on Thursdays at 8PM EST before moving on Mondays at the same time starting March 16, 2020. Filming began on July 18, 2019 and will end on April 2, 2020.
Executive producers Eugenie Ross-Leming and Robert Berens stated that the question of free will would definitely be part of the main focus over the course of the show's final episodes, as the cast grapples with the possibility that the God they thought they knew doesn't exactly have humanity's best interests in mind.
On March 22, 2019 it was announced that it will be the show's final season.
The epic journey of the Winchester brothers come to a close as Supernatural enters its final season. Sam (Jared Padalecki) and Dean (Jensen Ackles) have battled demons and angels, mythical creatures and monsters, in a seemingly unending quest to save the world. But in the final battle of the show's 14th season, they face off against God Himself (Rob Benedict), refusing to kill their surrogate nephilim son Jack (Alexander Calvert), and thus bringing about God's decision to end this reality once and for all...
