Yeah, Silence of the Bats was in jest. [Spoiler] I do think the Clooney cameo was also more of a joke than anything. Also all the BTS stuff in the article about the scenes from other movies with Keaton taken out was super interesting. I would really have liked to see the Batgirl movie. I also wonder how integral a part Gunn was in all these decisions or if they happened prior to his involvement.
Though, now I'm thinking who could play a super old Batman, maybe Hopkins isn't such a bad choice (though a buff Anthony Hopkins would be pretty distracting if he had to get in proper Batman shape), or would he be a better old Riddler or something?
I feel like you'd like Ted Lasso, also second the users who've said Ghosts (both US and UK).
