Choreographer Vishnu Deva feels 'Sarbjit' was the most difficult film for him to handle.

He says, "Sarbjit was tough because of its hard hitting story. Aishwarya Rai and Randeep Hooda specially impress with their energy in the 'Tung Luk' track in the film. We've tried to give a fresh look to the Punjabi song."
Vishnu Deva, who considers Prabhu Deva his guru, is the brother-in-law of veteran choreographer Ganesh Acharya.
