IMAX head blames "cannibalization" (not the kind you’re thinking of) for Black Widow’s box office
It’s not flesh-hungry humans that hurt Black Widow, but rather Disney releasing it on Disney+ and theaters simultaneously

For the first Marvel movie in more than two years, the release of Black Widow was pretty muted. It only feels like yesterday that we were watching other Disney properties congratulating the Disney property Marvel for making a lot of money. “Good job on the money making, me,” the posts implied.
After a whole bunch of handwringing about why Black Widow failed to be the box office bonanza of the pandemic, IMAX CEO Rich Gelfond blamed Disney’s release model. Instead of releasing Black Widow in theaters and letting it play for a few weeks, Disney dumped the movie in theaters and on Disney+ simultaneously. While they were hoping for boffo B.O., what they got was a whole bunch of piracy and lower-than-expected grosses (though, $300 million still seems like a fine consolation prize).
Per Deadline, Gelfond told listeners of the company’s second-quarter earnings call today that Disney, basically, blew it by experimenting (and by “blew it,” we mean, “only made $316 million in less than a month”). “Every studio has seen the same data that Disney has seen,” Gelfond said. “What Disney did is experiment during the pandemic, which is what they said they were going to do.”
