Imran Khan, who is making a comeback to the silver screen after almost two years with Nikhil Advani’s Katti Batti, says shooting the “Lip to lip” song with Kangana Ranaut for the movie, left him “exhausted”. Lip to lip, which is the third song in the film after Sarfira and Sau aasoon, is touted to be the first song in India where stop motion technology has been used. Kangana and Imran are said to have kissed each other for a collective 24 hours over a period of three days in order to get the right frame for the song. “It was very exhausting. It looks gorgeous, but it’s one of the most physically demanding thing that I have ever done because holding the body in that position static through the day and not moving at all. At the end of every day, we felt like our back was about to break,” he said.
