I've seen a lot of postings (not necessarily here but in other places) saying that if BW doesn't make this or that in the theater then it's a disappointment. I've also seen people in other places and articles on the lines of "OMG, this movie may only make as much as Doctor Strange or even Ant Man and Wasp-the travesty". None of these articles or posters take any account for the pandemic, restrictions in seating, the fact that Canada still has many of its theaters on lockdown, and the fact that there is a tropical storm flooding many parts of the northeast. This is all not to mention that anyone with D+ can order it for their families for $30 and save the hassle of theaters, food, etc., that would cost more in most cases. From my perspective, the $85-$90 it will probably make (maybe more) this weekend is an immense triumph. Add to that the fact that anything it makes on D+ (which will be more than any other PA release) will go straight into Marvel/Disney's pocket. Total revenues will end up being quite a bit more than it likely would have been in just theaters.
WW, if it makes $150 million this weekend, Disney's take-home would be approximately $75 million. Then, if 10% of D+ subscribers buy it, that would add another $300 million. That's $375 million in the bank.
If it weren't released on D+ and the same number of people all went to the theater (unlikely), it would bring in a "take-home" of $225 million for Disney (assuming 50% of revenue goes to the theater on average).
