James Gunn said he was called back for “Guardians Of The Galaxy vol. 3”, “The day after he signed on for The Suicide Squad”.
James Gunn had a brief outing with Marvel in the year 2018. According to EmpireOnline Gunn made some “historic offensive joke tweets” that caused Marvel to prevent Gunn from working on any more of their projects. However, Gunn’s hiatus from Marvel did not last long. Gunn told Empire.
“It was a happy ending, but it was also scary, because I actually got the call from Alan Horn long before it was announced: it happened literally the day after I agreed to do The Suicide Squad,”.
