Logic is there are many countries like Australia, US, UK, Africa, Gulf and other countries worldwide wherein the rights have been bought, so it is impossible to count by number. For example, ‘Dookudu’ released in 21 theatres in north India and it is heard that producers also didn’t know for three days.
In AP state ‘Dookudu’ touched 617 while ‘Oosaravelli’ touched 620. And with places like Bangalore, Mysore, Gulbarga, Chennai, Coimbatore, Madurai, Cochin also screening the film, who can give the exact count. On the other hand, the multiplexes give the count on the basis of screenings. Some theatres only have 1 show, can that be counted.
Some theatres in other states and countries count 4 shows as 4 screens. So, it is hard to give the count exactly. Once rights are sold it is upto the distributors to release in how many theatres they want. Finally, whatever count they give tends to get recorded. So, maybe the exact count within Andhra Pradesh is possible but giving overall count in exact numbers is not.
