PK is easily the biggest release at least in multiplexes surpassing Happy New Year and Kick. In Single Screens release count is just below Kick and Happy New Year. Overall film release count is over 4000 screens as final allocation is done. Thus, film is on par or little above the release size of Kick and just little below Happy New Year. Actual may be in the region of around 4100 screens.
Plus film has manage to get a good hike in ticket prices as majority of exhibitors have agreed all the terms of producers. Only few disagreed and hence kept it away from screening in their theaters. Generally ticket prices are hiked on average around 5-10%. But in case of PK it has managed to get over 10-15% on average which is substantial.
So, looking at all the factor PK has now all the potential to be a box office hurricane in coming days. As film is opening on normal weekend, will open below HNY. But if film content is good, then expect film to collect huge over the first week as Christmas Holiday falls on weekdays.
