FX, Donald Glover and his brother Stephen Glover have agreed to “part ways” with Marvel Television’s planned animated series “Deadpool,” the cable network said in a statement.

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

The Glover brothers were initially on board to write, executive produce and act as showrunners on the animated adult action-comedy series that was intended to launch later this year on FXX.

In May 2017, the network had ordered the series for a 10-episode first season, its second outing into Marvel territory. Its first superhero-based show, “Legion,” takes place in the “X-Men” universe and was renewed for a second season. Deadpool is also from “X-Men,” so this will continue FX’s relationship with the mutant-verse.

On the flip side, Ryan Reynolds will be returning as the title character in the feature film “Deadpool 2,” which hits theaters on May 18.
