You tend to see many non local actors and actresses in Tollywood and when you watch them onscreen, you can make out that they are not using their original voice. There are also those who have expressed few times that they are willing to dub for their own voice if given a chance.
However, it is heard that one big star declined to dub for his own voice despite having the opportunity. He is none other than Malayalam superstar Mohanlal and the film in discussion is Janatha Garage featuring young tiger Junior NTR in the lead.
According to reports, Mohanlal refrained from dubbing because he felt his modulation would not be able to justify the intensity of his character. Those who heard this say this is indeed a great gesture from Mohanlal who believes in perfection. His original voice was heard in the other movie Manamantha though.
