In the movie, I observed that the voice of Tina Munim (Kusum) was taken from Poonam Dhillon (Sunita). Was Tina's voice dubbed by Poonam Dhillon in the entire movie? This was a crucial point in the movie storyline too.
Yes it was... I felt that way as well even though i didn't understand the language. There was consistency in the voice comparisons between Kusum and Sunita, and so its possible that Sunita's voice was dubbed at some segments of the movie. I believe however that Sunita's voice was not dubbed for kussum in the scene were Vikram came into her room. I believe that was Tina Munim's voice
