Disney+'s new Marvel series Loki has officially begun production.

Series star Tom Hiddleston made the announcement by posting a photo of himself with the creative team behind the series. "Team Loki. Prep has officially begun! See you in the New Year," he wrote. Among those featured in that photo are series director Kate Herron and producer Kevin Wright.

Plot details for the series remain under wraps, but rumor has it that it will involve time travel. Sophia Di Martino was recently added to the cast, and may be portraying a female version of the trickster.

Loki was last seen in Avengers: Endgame, escaping with the Tesseract in an alternate timeline. The series is expected to follow that version of the character, meaning it will not be the same Loki as the one from the Thor films and the other Avengers movies.

Aside from The Falcon and the Winter Soldier, Disney+ also has The Falcon and the Winter Soldier, WandaVision, Hawkeye, Ms. Marvel, She-Hulk, Moon Knight and What If...? in development.

Loki, starring Tom Hiddleston, is set to hit Disney+ sometime in Spring 2021. Rick & Morty writer Michael Waldron will write the series and be billed as creator, with Sex Education's Kate Herron directing all the episodes.
