Ram Gopal Varma says that recreating the 26/11 Mumbai attacks, which claimed 166 lives, for his film was "terrifying".

"Just shot the Taj massacre of 26/11. Merely recreating it felt terrifying. Can't even imagine what the victims would have undergone, " Varma tweeted Monday.

The movie, being made at a budget of Rs.40 crore, went on floors in March. It aims to bring forth every aspect of the dreadful attacks in which 166 people were killed.

Varma reportedly wanted to shoot some portions at The Taj Mahal Palace and Tower, which was one of the key spots of attack, but he was reportedly denied permission to film there.
