features Alia Bhatt locking lips with Arjun Kapoor and its producer Karan Johar says kissing scenes help in luring the audience.
Earlier kissing scenes were not included in promos, but it has become a trend now.
When asked about the same, Karan said: "It's great these kids of the new generation are kissing on screen. It's the new ethos... but senior actors didn't do this. I like to watch kissing scenes, it's wonderful. Kissing scenes help to get opening and people also like to see it, so it's all about kissing."
The trailer was launched Friday. Abhishek Varman has wielded the megaphone for the big screen adaptation of Chetan Bhagat's bestseller.
This is his directorial debut and Karan said: "Abhishek assisted me during My Name Is Khan and I knew he has the sense of aesthetic. I went with my gut feeling."
