In September 2018, Marvel Studios was working on several limited series for the Disney+ streaming service, owned by the Walt Disney Company, focusing on secondary characters from Marvel Cinematic Universe (MCU) films such as Scarlet Witch. Variety reported that actors playing the characters in the films would reprise their roles in the limited series, including Elizabeth Olsen as Scarlet Witch, and that each series would have six to eight episodes, with a “high budget” on par with film productions. In addition, the series would have been produced directly by Marvel Studios rather than marvel Television, which had produced the previous television series of the MCU, also following the closure of the latter, incorporated into Marvel Studios on December 10, 2019. It was reported that Marvel Studios president Kevin Feige would play an “active role” in the development of each series, focusing on “continuity of the story” with the films and the actors who would reprise their roles from the films. 

In conjunction with each series, episodes composed of clips are published on the platform that have the purpose of summarizing the salient moments of characters and objects protagonists of the same; the television miniseries is called Marvel Studios: Legends.
