Kareena Kapoor got cold feet when she had to jump into a moving train while filming for Imtiaz Ali's yet untitled film.Interestingly, the actress has never boarded a train in life, and so was extremely nervous about getting crushed under the wheels of the train. A unit member says, "Bebo was not very comfortable while filming the scene. She faltered a few times, which was quite scary. Unfortunately, the speed of the train was not under our control. That's when our director Imtiaz said that he didn't want any mishaps on the set. So he suggested that we scrap the scene." However, Kareena refused to compromise and decided to enact the scene. After a few failed attempts, she managed to swiftly jump into the train. Eventually, she got the scene right. The producers (Shri Ashtavinayak Cinevision Ltd) say, "Kareena was a little nervous initially. But later she gave a perfect shot."
