This is from the distributors -
"While Avengers: Age Of Ultron too will have outstanding numbers from its India theatrical release, it may not be as big as Fast and Furious 7, courtesy a very simple release – the relative release size! While Fast and Furious 7 had released on the E-Cinema projection systems too, Avengers: Age Of Ultron will limit itself to the 2K digital projection platforms only, like all the major Hollywood film studios do. So, against the 2300 (approx) screens that Fast and Furious 7 released in, Avengers: Age Of Ultron may release only in about 1200 screens. However, if you look at the screen-wise collections, I’m quite sure Avengers: Age Of Ultron will score well over Fast and Furious 7."
