Sushant Singh Rajput and Amrita Puri in a still from Kai Po Che.
The film shows lead actors Sushant Singh Rajput, Raj Kumar Yadav and Amit Sadh as best friends.
Sushant Singh Rajput who plays the character Ishaan in the film, looks promosing in the trailer.
The film portrays the journey of three friends as they discover cricket, religion and business in their respective fields.
Set against the backdrop of religious politics, the story underlines the three mistakes made by Govind.
The film as well as the book is set in Gujarat, so the title Kai Po Che.
Amrita Puri will also be seen in the film.
Actor Sushant Singh Rajput says he and girlfriend Ankita Lokhande are not married yet and that the whole world would know when they decide to take their relationship to the next level.
"I've been hearing those rumours for three years now. Why would we hide our marriage when we're so open about our relationship? When we get married we'd let the whole world know, because we've nothing to hide in our relationship," laughs Sushant.
And there would be three wedding receptions -- in Patna, Indore and Mumbai -- when the wedding happens.
The couple, who met on the sets of TV show Pavitra Rishta, has been dating for the past four years.
At the moment, the actor says, Ankita is extremely excited about his Bollywood debut with new film Kai Po Che!, which releases Friday.
"She is much more excited about Kai Po Che! than I could ever be. According to Ankita, I am already a star. This is one time when I am not arguing with her," chuckles the far-from-nervous movie debutant.
While Sushant is hosting a special screening of the film for his family and friends in Patna, he plans something similar in Ankita's hometown Indore too.
"If there is a screening of my film in Patna there has to be one in Indore as well. Indore is my girlfriend Ankita's home-town. To me there is no difference between her hometown and mine. If I have a screening in Patna I must have one in Indore as well. Her family and friends are mine," he said.
