Creator ofHarley Quinn,Patrick Schumacker,previously hinted at aSuicide Squadcameoin the upcoming season, though he was hush-hush aboutwhothe special guest star would be. The announcement was made back in March of last year, meaning both Schumacker and Gunn have had to hold on to the secret for quite some time. And in Schumacker’s original announcement, he indicated that the guest star would be quite out of the left field. “I don’t think anyone will see him coming.” Schumacker tweeted. “I’ll withhold his identity, so you #DontGetTooAttached too soon.”

And indeed, Gunn’s turn as an animated version of himself is quite unexpected as he is, well, so behind the scenes, as most writer-directors are. Many fans, at the time, looked to stars such asIdris ElbaandJoel Kinnaman. However, Schumacker quickly shot those rumors down, giving the now very obvious hint that the guest star would be voicing himself. After all, Gunn was the only one inThe Suicide Squadwho performed his role as himself. But that’s one of the perks of being the film’s writer and director.

No premiere date for Season 3 ofHarley Quinnhas yet been set. However, it is set for a 2022 release. And this latest announcement seems to be geared at revving fans up for the newest adventures of their favorite clown-core troublemaker.
