Girish Johar, who is aware of the economics of the Hindi film industry, tweeted "#PK does a 50crs+ in flat 2 days - is now the 4th film of 2014 to get 50crs in 2days - #HappyNewYear #PK #SinghamReturns #Kick."

The  film, which also stars Anushka Sharma, Sushant Singh Rajput and Sanjay Dutt, did better on second day by earning Rs 29 crore, said Rajesh Thadani of Multimedia Combines.

"It has collected at least Rs 55 crore in first two days. On the first day, it earned about Rs 26 crore. The next day, it managed to mint Rs 29 crore. They will earn profit, but expectations were higher," he said.
