It showed 3000 screens on the movie page until about 7-8 days before release when actual nos came in at 3489.
So am assuming a similar 500 increase at least should be possible for SUPGR (ofc the 2500 no i read a month back or so could be a wrong starting point) as well when estimates turn to actuals but the question still remains - in a packed summer schedule, with multiple 'tentpoles'/big studio big budget releases, how many screens maximum can you possibly increase (if you want to - esp after seeing good tracking/initial response) in the last couple of weeks pre-release?
