Loki season 1 (2021) After stealing the Tesseract, an alternate version of Loki is brought to the mysterious Time Variance Authority (TVA) to help fix the timeline and stop a greater threat, ending up trapped in a crime thriller of his own making, traveling through time. By September 2018, Marvel Studios was developing a limited series starring Tom Hiddleston as Loki, which Disney CEO Bob Iger confirmed that November. In February 2019, Michael Waldron was hired as head writer, and Hiddleston was confirmed to reprise his title role. Filming began in February 2020, with Kate Herron directing the series, but was suspended that March due to the COVID-19 pandemic. Production resumed in September 2020 at Pinewood Atlanta Studios, and concluded in early December. The first season of Loki premiered on June 9, 2021, and ran for six episodes, concluding on July 14, 2021. A second season is set for release in mid-2023 as part of Phase Five.

Jeffrey Wright was revealed to narrate the series as the Watcher that July, with voice recording beginning the next month. Production continued remotely during the COVID-19 pandemic, with on-site work suspended. A. C. Bradley serves as head writer with
