After stealing the Tesseract during the events of “Avengers: Endgame,” an alternate version of Loki is brought to the mysterious Time Variance Authority, a bureaucratic organization that exists outside of time and space and monitors the timeline. They give Loki a choice: face being erased from existence due to being a “time-variant” or help fix the timeline and stop a greater threat.
Set in the Marvel Cinematic Universe (MCU), it shares continuity with the films of the franchise and takes place after the events of the film Avengers: Endgame (2019), in which an alternate version of Loki created a new timeline.
Tom Hiddleston reprises his role as Loki from the film series, with Gugu Mbatha-Raw, Wunmi Mosaku, Eugene Cordero, Tara Strong, and Owen Wilson also starring. By September 2018, Marvel Studios was developing a number of limited series for Disney+, centered on supporting characters from the MCU films.
A series featuring Hiddleston as Loki was confirmed in November 2018. Waldron was hired in February 2019, and Herron had joined by that August. Filming began in January 2020 in Atlanta, Georgia, but was halted in March 2020 due to the COVID-19 pandemic. Production resumed that September and completed in December.
