Black and White, Mission Istanbul, Amir and Mumbai Meri Jaan have plots touching upon instances of terrorism like the Mumbai commuter train bombings in 2006.

But all four films also explore the human side of the 'terrorist' - the moments of indecision and emotional upheavals in their lives.

"The person who has chosen to be a terrorist or someone who is forced into it or got caught in the loop are all humans in the end," filmmaker Raj Kumar Gupta said.

"They also have passions and emotions and suffer from guilt and indecision," said the director of Amir, the story of a man unwittingly ensnared in a terror plot.

Subhash Ghai's Black & White, which opened in cinemas on March 7, probes the mind of a would-be suicide bomber in New Delhi while filmmaker Apoorva Lakhia's Mission Istanbul is inspired by global terrorism.

And Nishikant Kamat's Mumbai Meri Jaan relives the horror of the train bombings that killed 187 people in Mumbai.

The directors said their films would promote mutual co-existence by depicting the suffering of victims of terror attacks.

"The implications of terror are very deep," Lakhia said during an event in Mumbai. "It affects so many people from the victims, to their families and even to those associated with terrorists."

The films do not point fingers at any particular terror group and filmmakers said taking a balanced approach was necessary.

"You cannot say one party is right and the other is wrong as both think they are correct in whatever they are doing," Lakhia said at an event in Mumbai.
