Is he trying to cash in on Saif's Khan surname?
"Well yes, right now I would want to cash on that and I hope it turns out to be true. We are very lucky that he has come on board to make this film because, like I said, it is a unique film, " said the 29-year-old, who is currently dating Saif's younger sister, actress Soha Ali Khan.
"Initially when we told the story to other people, they were sceptical about it. But he (Saif) believed in it and he is also doing a special appearance, " he added.
Meanwhile, "Go Goa Gone" also features a car in a special role. Kunal reveals special auditions were held to choose the car.
"You'll see the whole role of the car when you watch the film. But we thought, just like we are auditioning for actors, we should audition for a car as well because the car also plays an important role in the film, " said Kunal who was last seen in "Blood Money".
"There were 120 cars and we wanted a car that goes with the theme of the film, a red car and all, " he said.
Asked if they are following the trend of car films like "Ferrari Ki Sawaari", Kunal said: "Our film's USP and the main characters are the zombies. After that we come and then the car comes. The film is not about the car. It's a zombie-comedy."
Directed by Raj Nidimoru and Krishna D.K. of "Shor in The City" fame, "Go Goa Gone" also stars Vir Das and Puja Gupta. While Vir was last seen in "Delhi Belly", Puja was a part of "F.A.L.T.U.".
