If grapevine is to be believed, the unit of 'Rock On 2' saw some real life drama when co-actors Purab Kohli and Arjun Rampal indulged in a major spat on set over creative differences. Confirming the news an on-set source said, "Purab and Arjun had a spat in front of the entire crew. When things got nasty, the two actors decided to make a quick exit from the location. The shoot came to grinding halt following the episode. Farhan was present on the sets and had a shot with both actors for a live concert sequence. He met them in their respective vanity vans and managed to calm them down. The shoot then went smoothly with all three actors sharing the stage."
