Buddy, HBO Max is US exclusive service. It may have Spanish LA, Portuguese but that's it.
First of all it's not officially announced, its just a prediction by Deadline author's Sources. Secondly even if it's true,is that enough? Who will go to theatres for a movie which was already seen on a OTT platforms. And is that even making sense? If that's a PVOD release like Disney's Mulan, then OK they can do, but it's not it. That 30-60 day is nonsense.
