To call 'Kaliyattam' just a regional adaption of Shakespeare's 'Othello' would be doing great injustice to it. Jayaraj's focus on bringing to the fore the nuances in the interplay between characters pays off beautifully, complemented by wonderful acting by the lead characters. Suresh Gopi returns the performance of a lifetime as the lead (Othello) and Manju Warrier is totally convincing as Desdemona.
But Lal(as the cunning & wicked-hearted Iago) steals the show. The film is very well localized and imbibes the spirit of Shakespeare's original but still stands on its own by retaining its Indian cultural influences.
Though my native language is not Malayalam(the language spoken in the Indian state of Kerala), i found it easy to appreciate the movie, and like other great movies, you don't really need a sub-titled version to be able to enjoy the movie.
In short, i would recommend this movie highly to all movie lovers across the world.
