"I had a great experience working with Varun. He is a bundle of energy that inspires me," Nawazuddin said on the sets of the TV show 'Savdhaan India - India Fights Back'.
The intense revenge drama, directed by Sriram Raghavan, features Nawazuddin in a negative role. He feels "thankful" as he has got to work with Raghavan, whom he calls "one of the brilliant directors of the country".
"I always wanted to work with him and I thank god that I got to work with him in a wonderful script like 'Badlapur'," he added.
Also starring Huma Qureshi, Badlapur will hit the theatres on February 20.
