Choreographer Shiamak Davar, who choreographed Hrithik Roshan and Aishwarya Rai Bachchan in 'Dhoom 2', said they both were not used to his style of choreography. "So in the beginning phase where Hrithik had to dance, it was a bit difficult for him, but I must say he picked it up so beautifully and did such a good job," he added.
