Now, it is an open secret that Suriya is playing the role of conjoined twins in the movie 'Brothers', which is set to hit the screens soon. But the buzz is that the actor's younger brother Karthik Sivakumar has dubbed for one of the characters in the movie.

"While the Tamil version 'Maatraan' has Suriya dubbing for both the roles, the Telugu version has Suriya speaking for one of the characters and Karthi for the other", sources say.

They further add, "Recently, both Suriya and Karthi took a flight from Chennai to Hyderabad and dubbed for 'Brothers'. Both the actors spoke Telugu fluently and it was a stunning performance."

Directed by K.V. Anand and music by Harris Jayaraj, 'Brothers' has Kajal Agarwal as the leading lady. The movie is all set to release in Telugu and Tamil on October 12.
