While 3 Idiots - Tamil version will have Ajith in the prime role, its not yet clear whether Vijay will co-star with him in this movie, but it was previously confirmed that Simbhu is in the project.

Now Simbhu is out from it.

Simbhu, justifies his ouster by saying "I have lots of fans of Ajith and I am a Little Super Star. If Vijay is in the movie then Super Star Next and Little Super Star's presence will kill the appeal of Ajith. So I voluntarily got exited from the project"
