I think there are two important numbers; The numbers potential seats sold, and the number of seats required to book the Film.
So a active proposal might look this this;
I would like to see < This Movie > at this <Theater/Screen>
Until the required number of seats are sold it is just an active proposal, for people to search for, comment on, and particpate in by buying a possible ticket, and go to the show when (it is booked !!)
