Ans. It has been postponed and new release date is not announced yet. Fan is likely to release in first half of 2016.
Ans. PK was released in 5200 screens while Happy New Year was released in 5000 screens (Both Hindi & Regional). Bajrangi Bhaijaan & Dilwale can get up to 5500-6000 screens in India.
Ans. To break PK record content should be very solid. Dilwale will get earth shattering opening and if it sustains very well after first week which depends upon content of the film, then it has a chance. Anyway Dilwale should be targeting 300 crore club first.
Ans. For Brothers any thing less than 150 crore will be disappointment. On the other hand Singh Is Bling will be depending on hit music.
