Sivakarthikeyan, the new-gen leading star of Kollywood, delivered a brilliant dark comedy thriller 'Doctor' directed by Nelson Dilipkumar became the first blockbuster in Tamil cinema post the second wave. The film opened to a positive response from both the critics and the family audience.

Yogi Babu and Redin Kingsley played the lead comedians and gained high acclaim for their roles.

Redin Kingsley, who played Bhagat in Doctor, in a recent interview said, "I met Vadivelu sir. He has seen all my comedies. He appreciated my comic timing and said that I am doing well.” He has also shared that the true validation came for him when he got a call from Vadivelu’s team for a role in the actor’s upcoming Naai Sekar Returns. Redin also added that Superstar Rajinikanth appreciated his spontaneity while shooting they were shooting for Annaatthe.
