Music director Pritam Chakraborty was supposed to compose the music for Dhoom 3 and Ek Tha Tiger, both YRF films. But since the music of both the films needed to be composed simultaneously, it was difficult for Pritam to work on both the projects at the same time.
Besides, Pritam has a line up of other movies like Players, Tezz, Barfee, Race 2, Once Upon A Time In Mumbaai 2 and Jannat 2, so it was difficult for him to compose both Dhoom 3 and Ek Tha Tiger at the same time. Hence, he requested producer Aditya Chopra to excuse him from one of the films.
Since Pritam has worked on the Dhoom franchise from the beginning, Aditya Chopra told him to work on Dhoom 3 and leave Ek Tha Tiger. Pritam also agreed with Aditya's decision.
YRF has now roped in music director Sohail Sen to compose the music of Ek Tha Tiger.
Sohail Sen was the music director of YRF's recent release Mere Brother Ki Dulhan. Aditya Chopra was really impressed with his work and asked him to compose the music of Ek Tha Tiger and he gladly agreed to do so.
There is no animosity between Pritam and Sohail. In fact Pritam was really happy that Sohail has been chosen to compose the music of Ek Tha Tiger. Pritam said, "I really like Sohail's music and wish him all the best with Ek Tha Tiger."
