Varma intends to release it early 2013 in both Indian and international markets. So, it made sense for the filmmaker to launch the first look now, three days before the fourth anniversary of the terror attack.
"We are showing a 15-minute sequence of the opening which will clearly establish the purpose and the intent why a film on this subject was made," Varma told IANS.
"Also, a trailer (will be shown). We are also inviting some policemen who were involved in those attacks and the immediate survivors for the launch," he added.
The event will be held just two days after Pakistani Ajmal Amir Kasab, the sole Pakistani terrorist who was caught in Mumbai, was hanged in Pune Wednesday.
Varma has cast new actors for the movie.
"The cast is completely new along with some known actors (Nana Patekar) but the known actors were taken for their acting credentials rather than their existing image," he said.
According to Varma, the 26/11 siege that killed 166 people was more terrifying than the 2001 attack in the US.
"Never in the history of the world were there more terrifying attacks than those that happened on 9/11 in New York... But in the sheer audacity of their execution, I felt the attack on Mumbai was far more shocking.
"Many of us know of the attacks which happened in Mumbai but very few of us know how they happened and that is exactly what we felt should be known to everyone in the world," he said.
