Unlikely, but you never know. They don't seem too far apart.
"The Flash: Paradox" is going to establish a multiverse setting. I think it visits Tim Burton's '"Batman" and possibly 'Thomas Wayne' being 'The Batman' as 'Bruce Wayne' dies instead. I think that makes 'Martha Wayne' 'Joker' in that universe as her family has a history of mental illness.
That puts Todd Phillips' 'Joker' in another universe and we have to accept it. It's also why having multiple versions of 'The Batman' and 'Commissioner Gordon' is no longer a head scratcher using this DCEU tool.
And not that fans are ready for it, but on one of the alternate Earths there's 'Calvin Ellis'/ 'Superman' who has the Kryptonian name Kalel and happens to be President and a Black man.
Honestly it depends on the pathway they want to visit as there's multiple strands to use.
Sorry for the deep dive!
Thanks mate. Yeah just seems like style and tone are similar to The Joker, even with the film filer? ( don’t know the technical term). Thanks for the explanation so something like a DC version of the Into the Spidervse exploration.
