Prakash is busy shooting there for writers-turned-directorial-duo Sajid-Farhad's "It's Entertainment".
Said the source: "This is not the first time that Prakash Raj's dubbing was on hold while he shot for another film. During 'Dabangg 2', director Arbaaz Khan waited as long as he could to get Prakash Raj's dubbing dates and then got them dubbed by another dubbing artiste."
"Apu (Apoorva) didn't want to make the same mistake. Prakash's voice is too distinctive and familiar. He couldn't risk messing it up. If you remember in the original 'Zanjeer', Ajit's voice carried the villainous authority of the character. Prakash Raj's Teja couldn't speak in an impersonator's voice. So Apu flew down to Bangkok to dub the actor's dialogues."
