The topic of Batman's preference for the sexual act had hearts racing online when the co-creator for the adult animated series Harley Quinn, Justin Halpern, said DC Comics cut a storyline involving Batman performing cunnilingus on Catwoman.
DC's reasoning was "heroes don't do that."
Kilmer—who was Michael Keaton's successor as the Dark Knight in Batman Forever—became the first Batman to comment on the superhero's sexual debate.
He tweeted a GIF of himself as Batman and teased:
"Does he or doesn't he...?"
While his tweet was vague enough for interpretation, the GIF of his Batman telling Nicole Kidman's Chase Meridian—"We could give it a try. I'll bring the wine"—suggested the superhero might consider "going downtown" on a female companion.
And fans ate it up.
HBO Max's Harley Quinn pushes the envelope when it comes to graphic violence, profanity-laden dialogue and sexual activity depicted in the popular animated series.
But DC Comics draws the line when it comes to heroes performing certain acts in the bedroom.
Earlier this week, Halpern told Variety, "It's incredibly gratifying and free to be using characters that are considered villains because you just have so much more leeway."
"A perfect example of that is in this third season of Harley [when] we had a moment where Batman was going down on Catwoman. And DC was like, 'You can't do that. You absolutely cannot do that.' They're like, 'Heroes don't do that'."
"So, we said, 'Are you saying heroes are just selfish lovers?' They were like, 'No, it's that we sell consumer toys for heroes. It's hard to sell a toy if Batman is also going down on someone'."
