Don't worry, George Clooney's Batman will not grace our screens ever again (hopefully)
Absolutely not.

Assuming the above question was asked after 'The Flash' trailer was released and it confirmed the return of Batmen Ben Affleck and Michael Keaton, DCU co-head James Gunn shut that shit down real fast.
One can argue he only confirmed Clooney won't be the main new Batman, but I'm assuming this means he won't return again in any capacity. Feel free to speculate.
