According to The Hollywood Reporter, Waldron will serve as executive producer, write the pilot and act as series creator. Further, the series will reportedly focus on the titular trickster god as he shows up at various points in humanity's history, possibly influencing certain events during his visits to Midgard. This indicates that the series may have a more humorous tone to its narrative and may serve as a prequel to the first Thor movie. Whether or not Hiddleston will physically reprise the role or simply act as the narrator for the series has not yet been confirmed.
Aside from Loki and Rick and Morty, Waldron is also developing the series Florida Man for Paramount TV with Steven Soderbergh. He also wrote the spec script The Worst Guy of All Time (And the Girl Who Came to Kill Him), which is now being produced by Greg Silverman for Quibi.
Written and produced by Michael Waldron, the Loki TV series currently has no announced release date for Disney+, which launches in September.
