Kangana Ranaut, who will be seen as Payal in the film, feels that the story will strike a chord with the new generation.
"Writers have used elements like the battle of the sexes, issues of urban couples, expanded truth and non-linear narrative. We have UTV as the producers and I have worked with them in 'Fashion' and 'Life in a Metro', two of my most memorable films," Kangana Ranaut said in a statement here.
Imran, who will be essaying the role of Maddy, is eagerly waiting to start shooting for the film.
"My last outing with UTV was 'Delhi Belly' and we have worked together on many films like 'Jaane Tu Ya Jaane Na', 'I Hate Luv Storys' and 'Ek Main aur Ekk Tu'. We hope to recreate the magic with 'Katti Batti'. Nikhil is a great story teller and Kangana is one of the finest actors of our generation," Imran said.
Nikhil thinks the casting of the film is apt, going by its story line.
"I am elated by this casting combination as it is a dream to work with Kangana. Her body of work has not dulled her ability to bring humility to her craft. Imran is drawing from new personal experiences and emotions and brings with him a fresh approach," Nikhil said.
The film is about new age relationships.
"It's a most unusual love story steeped in the culture and language of today's relationships. We wanted to make sure that the script gets the right director and cast. We are thrilled to have Nikhil, Imran and Kangana Ranaut on board for the film," said Siddharth Roy Kapur, Managing Director, Disney India.
'Katti Batti' will go on the floors later this year and is scheduled for a worldwide release in 2015.
