1) It has Hrithik Roshan in the lead.
You don't make the silly decision of going up against a popular actor in Bollywood, you never do such stupidity. In India the actor is more important than the story and sorry to break it to you Shahid but Hrithik is much much much more popular than you.
2) Indian audience LOVE movies like 'Bang Bang'.
Why do you think Rohit Shetty has survived as a director till now? The Indian audience for some damn unknown reason loves to see exaggerated action sequences. I mean they don't even seem interested in the movie until the action part begins. People clap and whistle when Salman kicks 'someone' and that 'someone' goes flying in the air.
3) It is a remake of 'Knight and Day'
Well Knight and Day from which Bang Bang has been adapted was a great hit. The movie became popular worldwide and earned about USD 272 million.
4) Bang Bang's trailer created history
Bang Bang is the first Bollywood movie to cross 2 Million views on Youtube in just a time span of 19-20 hours; this was a loud and clear warning!
5) Shahid's luck is amazing
Shahid's luck is remarkable, he has had 6 break-ups in bollywood and none of his movies have worked for the audience. Kaminey is the only movie when we felt that there was 'A Shahid Kapoor' in the industry.
