Donald & Stephen Glover never got to make this under the old Marvel TV regime. Maybe they can now.
From Wiki:
>Ordered straight-to-series by FXX in May 2017 following the successful partnership of Marvel Television and FX Productions in making the X-Men spin-off series Legion, 10 episodes were planned for the series to debut in 2018. Donald and Stephen Glover had begun work in a writers room by the time of the series' announcement. Early animation had been completed for the series that August, with the Glovers wanting a distinct voice and tone from previous incarnations of the character including the Deadpool films.
They used Ryan’s voice when they could have had Donald record some quick lines. So while they were aiming for a unique “voice” for their show, that could just mean a different tone than the movies, and Ryan could still voice Wade.
>The announcement of the series, and the involvement of Donald Glover specifically, was met with enthusiasm from commentators. However, in March 2018, FX Networks announced that it was no longer moving forward with the series after Marvel decided not to pursue the version of the series that the Glovers were creating. This was widely seen as disappointing and was met with criticism, including from Donald Glover himself who publicly suggested that racism may have contributed to Marvel's decision.
Jeff Loeb has a history with racism and was the Marvel TV producer Donald is likely referring to, and was producing the show. But that prick’s not around anymore.
