In September 2018, it was reported that Marvel Studios was developing several limited series for the streaming service Disney+, to be centered on "second tier" characters from the MCU films who had not and were unlikely to star in their own films. Characters being considered for series included Loki and Scarlet Witch, with the actors who portrayed the characters in the films expected to reprise their roles for the limited series. Each series was expected to be six to eight episodes, with a "hefty rivaling those of a major studio productions". The series would be produced by Marvel Studios rather than Marvel Television, with Feige taking a "hands-on role" in each series' development.
