Disney didn't "stop" theaters from screening Black Panther this past/upcoming weekend. Like most Disney films, it's not available for second-run showings. It's long-standing Disney policy, and has effected films from the Fox film archives as well. ( https://www.latimes.com/entertainment-arts/business/story/20... )
Am I right in thinking this policy started under Eisner, or has it been going on longer?
Nobody else locks their old content up like Fort Knox, Disney.
