During the shoot of ‘Happy Ending’, Saif Ali Khan and Ranvir Shorey, both of them happened to get into a quarrel on a particular dialogue of Ranvir, that he was not convinced with. There was a small tiff which took place between them because of the dialogue in a particular scene.
It was said that Ranvir was not convinced with a certain dialogue of his and wanted some changes on it. However, Saif felt that the dialogues were correct and required no amendments at all. So therefore due to their disagreement, the atmosphere certainly was under a dark cloud, but both of them gave their shots without any interaction off the camera and wrapped it all up. After the shoot both the actors seemed to be sorted with each other and all was cool between them.
