I'm wary of assuming what Reeves is thinking or feeling right now. I would say that if I were in his shoes, I'd have some very real concerns. I'm seeing movies pulled from theatrical release and stuck on a streaming service instead, with the filmmakers finding out the same day that the general public does. I'm seeing a film that is permanently vaulted for "tax purposes," with the filmmakers once again finding out the same day the general public does. I see a CEO that is very keen on getting this shared universe thing figured out, meanwhile I'm over here with my self-contained universe featuring DC's most profitable IP (hell, one of WBD's most profitable IPs).
The creatives are not being considered in these decisions at all, and they're not even afforded the basic respect of being told ahead of time that these decisions are being made. Is that an environment I myself would want to be in? Who's to say it doesn't happen to me next? Hell, Reeves' plans for expanding his Batman universe via spinoff shows are already in serious jeopardy (if they're not already canned behind the scenes), so it's possible he's already seeing himself affected in some capacity.
I don't know. The man himself said he doesn't need to this, back when negotiations first fell through. If working with this new ownership proves to be a bigger headache than it's worth, he walks. I 100% believe that. My question now is, do I have the confidence that ownership wouldn't let it get that far? It's extremely hard to say. Zaslav isn't playing around. You either play ball with him or you're out.
