Theaters still have to report tickets sold and kick back roughly 50% of the ticket price, so you would need to cut that revenue number in half. Also I don't remember the exact timeline for Moviepass's various restrictions, but there was a limit on the upside at various times due to policies like preventing users from watching movies multiple times (which would generally cap the max tickets below 30 since most theaters don't get 30 new movies a month), limits on how many tickets can be purchased for a single theater that would lock users out from using that theater for the rest of the day, and users being suspended for "fraud" that was often reported to be just heavy use.
I can’t help but wonder if movie theaters could have exploited a similar loophole with MoviePass before they went bankrupt. Something like this:
1. Movie theaters buy up MoviePass subscriptions
2. They use those subscriptions to pick different movies to see every day at their location
If they picked 30 movies a month that would be approximately $450 a month in revenue (at $15/ticket), $440 of which would have been pure profit.
