Helstrom was canceled a year later in December 2020. Several more series were in development for the banner, but Marvel Television stopped work on these when it was folded into Marvel Studios in December 2019.

Labelled "Adventure into Fear", the series included Ghost Rider-starring Gabriel Luna, reprising his role from ABC's Agents of S.H.I.E.L.D.-and Helstrom, though Ghost Rider was dropped during development. Produced by Marvel Television and ABC Signature Studios, they were to be set in the Marvel Cinematic Universe (MCU) and acknowledge the continuity of the franchise's films and other television series.įollowing the cancellation of all Marvel's Netflix television series, Hulu ordered a set of interconnected new series from Marvel based on fear-focused Marvel properties in May 2019.
