Deadline is reporting that FX are no longer moving forward with a Deadpool animated series, which had Donald and Stephen Glover attached as showrunners.

Since the character made his debut in the comics back in 1991, Deadpool has grown to become one of Marvel’s most popular characters, especially with last years big screen outing with Ryan Reynolds in the title role where the R-Rated superhero film made $782m worldwide on a $58m budget.

In a statement from the FX network about the announcement, they said:

Due to creative differences, FX, Donald Glover, Stephen Glover and Marvel Television have agreed to part ways on Marvel’s Deadpool animated series. FX will no longer be involved with the project. FX and Marvel have an ongoing relationship through our partnership on Legion, which will continue.

It was announced in May of last year that the FX network had given a series order for an animated adult comedy series focused on Deadpool, which had Floyd County (animation house behind the Archer series) to handle the animation production for this particular project, while Donald Glover and Stephen Glover were on board to write, executive produce the series as well as serve as showrunners.

It’s unclear if Marvel intends to continue developing Deadpool as an animated series with on a different network….perhaps for the Disney streaming service next year?
