The Suicide Squad is winning over a lot of people and there had been early ideas to have Task Force X being assembled to take down Superman. However, the main threat of the film was the Borg-like alien Starro The Conqueror, who was able to control the minds of anyone that was unlucky enough to get one of the self-replicated mini-Starro attached to their face.
James Gunn has revealed to the Script Apart podcast (via Comic Book) that one of the big reasons they didn’t go with Superman was the studio’s uncertainty about Henry Cavill sticking around or what exactly their DCEU plans for the son of Krypton moving forward.
“There was a time when I thought The Suicide Squad should fight Superman. At the time, there were a lot of questions like, ‘Who is Superman in the DCEU? Is this movie outside the DCEU?’ I just didn’t want to deal with it all that much.”
This could also explain why the Superman cameo in Shazam! was a stand-in, despite that film clearly takes place within the Snyderverse/DCEU.
It’s revealed that Idris Elba’s Bloodsport put Superman in the ICU after shooting him with Kryptonite bullet, so at the least they were able to add that small connective tidbit.
Gunn explained why he wanted to use Starro.
“I think he’s a perfect comic book character because he’s absolutely ludicrous but also very scary in his own way. What he does is scary. He used to scare the crap out of me when I was a child, putting those face-huggers on Superman and Batman. So I thought he was one of the major, major DC villains that was probably never going to be put into another movie. And if they did, it’d have been a ‘black cloud’ version of Starro. Not a giant walking starfish, a kaiju that’s bright pink and cerulean blue, this ridiculously big, bright bad guy.”
The studio has indicated that they’re keen on working with James Gunn again on more DC movies, but that seemingly won’t Gotham City Sirens as the director downplayed recent speculation on Twitter.
