Until last week, comedian and television creator Donald Glover was working on an animated series for FX about the Marvel superhero Deadpool, a violent mercenary character known for his wisecracks and toilet humor.

By last week, the project had been canceled and Glover was on Twitter publicly raising more questions about what led to his departure from the show.

The project, planned as a 10-episode run for the FXX channel and announced in May, was to have been a collaboration with Glover’s brother Steven, another pairing of the siblings behind the show “Atlanta,” which airs on FX. (FXX is FX’s sister channel, and both are owned by 21st Century Fox.)

But on Saturday, FX, citing “creative differences,” announced that the project had been canceled. Its statement said the Glovers had agreed to part ways with the network and with Marvel television.

In an article about the announcement, Variety said the show “may have been a casualty of Donald Glover’s packed schedule.”

Glover, who also releases music under the name Childish Gambino, disputed that characterization in a tweet thread on Wednesday: “For the record: I wasn’t too busy to work on ‘Deadpool,’” he said.

He then posted pages of a script that used the Deadpool character — who is known for speaking to readers or moviegoers directly — to think through the cancellation.

In the script, which is filled with pop culture references, including several that allude to events from the last few days, Deadpool considers whether racism was a factor in the cancellation and remarks upon specific scripts that may have alienated the Glovers’ collaborators.
