Mentioned this to some people yesterday, but I will post it here as well.
Uncomfortable truth about this movie, is that while it was pretty big generally-speaking, it's still going to be a loss for Warner Brothers. Best to come to terms with that now so the Snyder-fans don't hurt ya later.
The simple truth is that this movie cost about 350 million dollars including the production budget and promotion/advertising.
It is currently just surpassing 500 million dollars at the global box office. Even if we assume it hits 600 million, WB will end up losing about 100 million dollars on it. The studio only makes 50% of domestic gross, and about 1/3'd of the international gross, if you're curious on how that happens. This is why it's usually safe to say a movie needs to make anywhere from 2 to 2.5 times its total budget to break even or make a substantial profit. For Superman, that would be 700 million to 900 million dollars.
Based on how things are going, it's probably safe to say that's unlikely to happen.
Movies like this are just so expensive to make nowadays, and the audience continues to get smaller as they become more untrustworthy of studios. Plus, with how quickly movies are moved to streaming services nowadays, many would rather just wait for the blu-ray or digital copies.
Then again, this is the first movie in the new DCU, so it didn't have as much of an established audience as say, the MCU. Especially overseas. And we all know how badly Snyder's DC went, so the audience has even less trust than usual.
It isn't all bad though. This movie reintroduced the universe to international markets, which could be especially good moving forward. It also DID surpass MoS in the domestic category, which means Americans are still intrigued, at least.
We'll see what happens in the near future.
