"We were aware that Saif comes with a good baggage of romantic comedies and love stories. So, we figured out that he is the right person to have a take on them. He plays a scriptwriter in the film who is against such stories but has to write one," Raj told PTI in an interview.
Raj and his co-collaborator Krishna DK, best known for their projects like '99', 'Shor In The City' and 'Go Goa Gone', found a willing partner in Saif, who was keen to work with them again after the success of the zombie comedy.
Raj says the movie, releasing this Friday, is a quirkier take on the genre of romantic comedies while also reflecting on their nature.
"We wanted to have a lighter take on romantic comedy. The film is very aware that it is a rom-com. We are hitting all the points till interval but despite being a bona fide romantic comedy, it goes beyond.

The film has Saif's wife Kareena Kapoor and his 'Kal Ho Naa Ho' co-star Preity Zinta in cameo appearances.
"It is very gracious of such established stars to agree for a cameo. It shows how secure they are. Thankfully, they liked their characters a lot. Kareena and Preity's presence lends certain authenticity to the story. Plus, it is fun to see real-life couple split on screen," Raj said.
The director also found a fun way to include Saif in a cameo role in his own film.
