I tried to see if anyone else gave a good explanation... but the gross receipts at the box office only tell how much money was received from tickets sold, not how much money was made. I do not know what percentage of the gross that the film company gets from ticket sales in this case. That can vary and is not what is being measured.
OK...I appreciate that...
Actually, I don’t really care...The last theater movie I went to see was “Ironman” in 2008...LOL
