"People ask me what is this film for you? I say that this film is my ‘Vaastav’ (which had Sanjay Dutt in the lead role). On a serious note, it’s a career defining film and it’s something that I have taken very seriously," the 39-year-old, who has lately been seen in comedies and dramas, said at an event here.

Directed by Sanjay Gupta, "Shootout At Wadala" also stars Anil Kapoor, Sonu Sood, Mahesh Manjrekar, Manoj Bajpayee, Tusshar Kapoor, Ronit Roy and Kangna Ranaut.

John, who has turned producer with "Vicky Donor", adds that he is having a great time with the team of his first production venture.

"I am enjoying a lot because my cast of Ayushmann Khurana, Yami Gautam and Anuji (Anu Kapoor) are super talented. Our director Shoojit Sircar, with whom I am doing my next film, we are all a great team. We are really having a great time and enjoying this," he said.

John’s last release was "Desi Boyz" and he is currently gearing up for Sajid Khan’s "Housefull 2" that hits theatres April 5.
