Sushant Singh Rajput had a dream Bollywood debut courtesy Abhishek Kapoor who gave him his first film Kai Po Che! In fact, the duo shared a great rapport and Sushant even considered Abhishek aka Gattu his mentor. However, things have changed drastically between this guru-shishya jodi and their equation is no longer the same. Not too long ago, Ankita Lokhande s beau walked out of Gattu s film Fitoor and decided to do Shekhar Kapur s magnum opus Paani.
