Siddharth is one Tollywood star who doesn't need others to dub his films in Tamil. He is a Tamilian and lends his own voice to all his Kollywood flicks.

However, for Sridhar, the Tamil version of Telugu hit O My Friend starring Siddharth, Hansika and Shruti, the actor has let another Tamil actor dub his parts. Upcoming Tamil actor, Sivakarthikeyan, has been picked for this job.

Sources said when the makers approached Siddharth to dub for the Tamil version, the actor refused.
The movie's producer, who is promoting Sridhar as a straight Tamil film, approached Siva for dubbing. "Siva's voice exactly matches Sid's. We are relieved," said a unit hand who has already seen Sridhar.
