Story:
12th century..
When Saivite intolerance against Vaishnavites was at its peak, An ardent Vishnu devotee Rangaraja Nambi (Kamal Haasan) loses his life when he attempt to stop the
Saivite King's act of throwing away Lord Rangantha's idol into the Sea.

Cut to 21st century..
USA based bio-scientist Govind (Kamal Haasan) is part of the team that produces bio-weapon.His boss sells the deadly virus to anti-social elements.Govind sensing the dangers of the weapon, which could potentially kill people instantly in a vast number, steals the sample weapon to destroy it. The Weapon vial is accidentally transported to India.Govind& the assasin Christian Fletcher(Kamal Haasan) come searching for the vial to India.In the course of the hunt for the missing vial, Kamal takes on 7 other characters .

Highlights:
As an actor,Kamal Haasan should be commended for his excellent effort to portray 10 different charecters(Rangaraja Nambi,Scientist Govind,George Bush,Raw office
Balaram Nadar,Assassin Chris Fletcher,Pop Singer Avatar Singh,95 year old lady Krishnaveni,Activist Vincent,7foot tall Muslim& a Japanese Kung Fu master) but as a
writer ( Story&Screenplay) he isn't impressive.
Visual effects(Brian M. Jennings) are exellent,Especially the Rangaraja Nambi episode &Tsunami episode in the climax are simply superb.
Makeup design(Michael Westmore) is very good,though it looked odd for some charecters.
Music (Himesh Reshammiya) is just average.Background score (Devisri Prasad)is good.
KS Ravikumar who directed Kamal's comedies Bhamane Satyabhamane, Tenali, Panchatantram is successful somewhat in creating some comic moments.But he failed to create a stellar experience audience expected from a movie with Kamal Haasan playing 10different roles.

Sidelights:
Asin looks pretty but her charecter is the most irritating part of the film.unbearable !
Kamal Haasan has a complicated idea that is too complex to understand for common audience. and he tried to narrate it with some thrill, comedy &suspense providing enough scope for
him to play 10 different charecters.But ,as a writer ,he failed miserably to deliver what audience expected from the movie.
The movie is lengthy(3hours) and tests your patience most of the time.

Public Talk : Disappoitment.Avoidable unless you are desperate to watch Kamal Haasan portraying 10 different roles.
Industry Talk : Won't appeal to Telugu audience.
