A 7 minute video of the movie was published over the Internet on November 23, 2012, two days after terrorist Kasab was sent to the gallows.
One of a number of dramatic film dramatizations about or based on or inspired by the 2008 Mumbai terrorist attacks. The films are (in order of release): Mumbai Massacre (2009) (which has been edited into the episode Mumbai Massacre (2009) of the US television series "Secrets of the Dead"); the short film Embrace (2012); the Hindi film Shahid (2012); the Bollywood movie The Attacks of 26/11 (2013); the French feature film Taj Mahal (2015); One Less God (2017) (a.k.a. The Mumbai Siege: 4 Days Of Terror); and Hotel Mumbai (2018).
Reportedly, the filmmakers shared some of the box office profits from the movie with the families of the victims families of the actual 2008 Mumbai terrorist attacks.
The India vs England 5th ODI at Cuttack (which India later won) was being shown on the TV sets inside the fishing yard and the Leopold café in the movie. The English team left the country immediately after the attacks, thus abandoning the 6th and the 7th ODI in the 7 match series.
The attacks at Chhatrapati Shivaji Terminus in the movie are actually shot and shown at Mumbai Central Terminus.
