Variety:

FX, Donald Glover and Marvel Television have all parted ways on plans to produce a “Deadpool" animated series.

The project was announced last May with a 10-episode order for the FXX channel. Glover was to have created the show with his brother, Stephen Glover. Those two are already collaborators on the much-praised FX series “Atlanta.“

FX confirmed the split on Saturday and noted that it remains in business with Marvel TV on the Noah Hawley drama “Legion,“ which returns for its second season on April 2. FX cited “creative differences" as its reason for bowing out of “Deadpool.“

Huh. Weird. Wonder if we’ll ever find out the “why” on this.
