The film was banned in India and was released theatrically only 2 years after its actual planned release date.
All the actors in the film had real names of the characters which they played from cops, politicians and bombers.
The film is based on true facts regarding the Mumbai Blasts in 1993.
The chase sequence in the movie was over 7 minutes long and considered as one of the longest chase sequence in Bollywood. The entire chase sequence involves no vehicle and mainly involved running around slum areas of Mumbai.
Anurag Kashyap stated "don't want to say anything about Sanjay Dutt's verdict - maybe I want to be politically correct. I have lot of opinion on many things, but I have decided not to express my opinion because I have faced repercussions. The world can't take honesty. My releases are blocked. I have been thrown out of my pet project - but I will not name them. Bill Gates once said, 'Life is unfair, get used to it.' That's all I want to say. My movie Black Friday doesn't have a Sanjay Dutt scene because Sanjay Dutt's story was not important to my film. He is important to the media. He is important to lot of people as he can sell things. I don't need Sanjay Dutt's story to sell Black Friday. It is about the blasts, not about the peripheral issues."
