When the team of Karthik Calling Karthik told Deepika Padukone that she needs to smoke for her role in the film, the actress was afraid of getting addicted to cigarettes. But thanks to Ritesh Sidhwani"s thinking, they shot for the scenes with organic cigarettes and the parts were done.
In the film, Deepika plays a modern girl who is a smoker and it's Farhan Akhtar who gets her to leave smoking. Because Ritesh ordered nicotine-free cigarettes, the portions were shot well. Since her character gives up smoking, the film carries a good message and won"t be promoting it.
