"'Vishwaroopam'. A man's dream to prove Indian cinema stands at par with the world. Kamal Haasan has put everything into it and I wish him the best. I am just happy to be a small part of Kamal Haasan's dream in 'Vishwaroopam'. As I watched him calm and resolute in crisis, I came to admire him much more," Kapoor posted on Twitter.
"Vishwaroopam", written, directed and produced by Haasan, deals with the adversities of war.
The Tamil and Telugu versions of the film were scheduled to release Friday, but the Tamil Nadu government Wednesday imposed curbs on it following protests from Muslim groups. Certain Muslim organisations protested saying the movie portrays the community in bad light.
The movie's Hindi version "Vishwaroop" will release Feb 1.
