"Thank you for the immense love and appreciation for 'Hasee Toh Phasee', a film I am extremely proud of," Karan tweeted Sunday.
The Siddharth Malhotra and Parineeti Chopra starrer came out Friday.
"In two days, 'Hasee...' collected between Rs.9 and Rs.10 crore. The Sunday collections will help decide whether the film is a hit or not," Rajesh Thadani of Multimedia Combines told IANS.
Gautam Dutta, COO, PVR Cinemas, believes that the genre and the young star cast worked in favour of the film that hit 1,500 to 2,000 screens across the country.
"It's a nice comedy genre and young actors are there in the film. It picked up well. The opening day saw around 70 percent occupancy, but the figure went up to 80 percent on weekend. The occupancy is good, the film has been appreciated," said Dutta.
Parineeti also expressed her happiness on Twitter and wrote: "Thank you for the amazing response guys! We sure are happy."
