I just now watched Manichitrathazh, the malayalam film from which Chandramukhi was remade, on Asianet. Chandramukhi has faithfully reproduced certain aspects of the film (A lot of aspects) ranging from dialogs, camera angles and dance steps in the song "Oru Murai..." However, it is evident that of these two, Manichitrathazh was meant to be a commercial film dealing with split personality and its treatment whereas Chandramukhi was meant to be a blockbuster dealing with split personality and its treatment.
On the whole I felt that Manichtrathazh had the concept better covered. There was none of the foolishness with shining light into the aflictee's eyes and stuff. It was a much more simpler and more down to earth affair. Shobana's dancing was excellent though the song could never be as good as the RaRa Sarasikku RaRa. But even this song took a thing or two from the original like the Mirdhangam that starts at the beginning of the song(That when first heard gives goose bumps, after hearing a few time gives pleasure and later, irritation). Moreover, in Chandramukhi, our Saravanan asks Ganga what her name is, what her surname is, etc after she has fully woken. However in the Malayalam movie Mohanlal asks the same when she is under hypnosis which is the correct way to go about in in such cases. This is because many times, a person may not be completely cured of Multiple Personality Disorder(MPS), as was portrayed at the end of the film Anniyan, which could be ascertained by hypnosis. Speaking about Anniyan, one could say that the film was a good adaptation of the book "Tell Me Your Dreams" by Sydney Sheldon.
On the whole, the Malayalam version is more accurate when it comes to technical details of dealing with MPS, than Chandramukhi.
DISCLAIMER: I do not subscribe to any of the above views which are merely the views and opinions of my alternate self. It does not in anyway undermine my view that the Superstar is the best actor that is and Chandramukhi is one of the best films I've ever come across. As always, viewer discretion is adviced when reading this blog.
