Hi MinaTakla,
Thanks very much for the post. So this means Dunkirk was overestimated by a whooping 145,000 admissions. It seems to be the issue for the rest of the titles as well. That's quite amazing!
Looking at the number, 2.5 mil admissions for Dunkirk appears to be out of reach. My hope is it will ultimately pass Wonder Woman.
By the way, I used Wonder Woman's total admission from cine-directors: 2,157,000 and the dollar gross from boxofficemojo: 17,238,368 USD and got 8 USD per ticket. This is way cheaper compared to us here in Australia: 15 AUD.
