"Just took the last shot of the massacre at CST (Chhatrapati Shivaji Terminus) station and with this, the film is completely done. Kasab and his fellow terrorist Ismail had killed nearly 65 people at the CST station and injured hundreds more," Varma tweeted.
Varma admits the film has changed the way he looks at people now.
"If the reel horror was looking so gruesome while I was shooting, I can't even begin to imagine how gruesome the real horror was," he wrote.
"The 26/11 film has changed me as a person in terms of my changed understanding of both human nobilities and also their evils," he posted.
