How different is Unnaipol Oruvan from the original?

The critically acclaimed Bollywood film A Wednesday is being remade in Tamil titled as Unnaipol Oruvan with Kamal Haasan and Mohanlal in the lead. This film is directed by Chakri. From what we gather from a few of the Unnaipol Oruvan stills, we see a marked difference from its original version.

While in the Hindi version the four actors that play the terrorist role were not identified with any religious affiliation in relation to their physical appearance, in the Tamil version all the four terrorists are shown to be in different get up each attributed to one religion. Probably Kamal wants the audience to know that religion and terrorism are not interrelated.
