Universal just has to buy MoviePass. Assuming it has the cash. From what I've read over the last few years, the big Hollywood studios are not cash-rich.
Hardly seems like a large barrier. I would think the biggest issue would be finding the card company to partner up with, and then it doesn't sound like a very high barrier.
For theatres it's even easier to offer an unlimited option since they can just have the accounts internally. Studios can partner with theatres, though that seems overly complicated (I went to Mission Impossible last night, so I need a paramount account?)
