A still from Pankaj Kapoor's upcoming movie 'Mausam.'

The release of 'Mausam,' which is Pankaj Kapoor's debut directorial venture, has been postponed to Sept. 23 "to avoid fragmented release."

The movie's hero, Shahid Kapoor, said: "We are here to announce the changed release date of our film from Sept. 16 to Sep 23. The reason for this is that we had applied for two permissions - a NOC (no objection certificate) from the IAF (Indian Air Force) and certification from the Censor Board. We got U-certificate from the Censor Board, but IAF gave us a conditional certificate because they wanted a 30-second scene from a particular sequence to be corrected."

The romantic film is based on the lives of two lovers -- a Punjabi Sq. Leader Harrinder, played by Shahid Kapoor, and a Kashmiri girl called Aayat, played by Sonam Kapoor.

Interestingly, the movie will bring out Shahid's ability to work under his father Pankaj Kapoor.

Reviews have already praised the music of the movie composed by Pritam. Rating it 4 out of 5, the Bollywoodhungama said: "Mausam is a fantastic album and has all the ingredients that make for a popular soundtrack. While 'Sajh Dhaj Ke' and 'Mallo Malli' are the pick of the lot when it comes to instant chartbusters in the making, 'Rabba Main Toh Mar Gaya Oye' and 'Ik Tu Hi Tu Hi' are good enough to enjoy a rather extended shelf life."

The question is whether Shahid could hit the box office jackpot once again after his 2007 blockbuster flick "Jab We Met".
