An interesting fact has been came out in regard to Nikhil Advani's next movie "Katti Batti".This has never happened before in any other movie. During the shoot of the climax, Nikhil came up with a new thing, so he used real reactions instead of script. He thus did bot give any script to the actors for the last 29 minutes. That is why everyone shot without script. Nikhil has done his for the first time. According to sources, the result has been good for this experiment. That was a good experience. In Katti Batti, Kangana Ranaut and Imran Khan are in lead role. The movie will release on 18 September.
