Bollywood famous actor Nil Nitin Mukesh has donned the villain role in the film Kaththi. For the first time, he has dubbed in Tamil. Nil Nitin Mukesh dons the role of a North Indian who speaks in Tamil.
A R Murugadoss felt that it would be appropriate if Nil Nitin Mukesh dubbed in Tamil in his own voice. So he asked Nil Nitin Mukesh to dub. He also accepted this as a challenge. In the last three days, he has completed dubbing for the first half of the film.
