The film has faced objections from Sikh campaign groups because of its portrayal of the religion.
He told IANS: "The creativity of the film has not been affected in any way. Every film is rectified, sometimes it's made even better.
"The objectionable things were very small. The writer and director of the film is Punjabi and we took care of things. Even the guy who tied my turban was from Punjab."
In August, the star denied that the film is offensive to the Punjabi Sikh community in India.
The All India Sikh Students Federation (AISSF) had called on its religious clergy to take official action against the film.
