How do you reserve film tickets

I'm a Chinese teacher and is going to teach students on the topic of "how to reserve film tickets"? I know in China we use an app to find a movie, choose seats, and pay through Alipay.

But how do you reserve film tickets now in your country? What information can you find in an app if you can use it?

I feel uncertain about the terms and phrases used in this process, So if possible could you tell me some more about the information you can read on your phone? for example, do you say "the movie is on in movie hall 2", or "played in the 2nd hall/movie office"?
