A psychiatrist in Chandramukhi (2005)
Directed by P Vasu, Rajnikanth got a chance to play an author-backed role as Dr Saravana, a psychiatrist.
The movie might have been a remake of the Malayalam film Manichithirathaazhu but the role was shaped to suit a superstar.
While Nayanthara provided the romantic angle, Rajini found time to delve into psychology, manias and phobias. He also provides a successful explanation and cure for Jyothika's mental illness -- even going to the lengths of sacrificing himself.
Again, Rajini's impeccable style and panache carried him through what was essentially an intellectual role -- though it had its fair share of fights and songs.
