People will not be going to movie theaters for a long time. It might be 5 to 6 months before theaters open again. In the meantime they will be getting their movie entertainment at home, from cable and streaming new films. I see one of three possibilities. 1) It all goes back to normal, with the number of movies and attendance back to pre-virus numbers. 2) People learn a different behavior and prefer to watch things at home, dropping the attendance at Cinemas. or 3) There is a great pent up demand, and people flock to the theater when this is over.
Other factors are how many theaters are left in business and how many people have jobs to afford to buy a ticket.
