Inspired by Lock, stock and two smoking barrels??
The basic outline is a perfect match!!
Hero is a gambler( racing here and poker there). Story is centered around drugs, money and 2 diamonds. ( LSTB: Its about weed, money and two guns ). All the bad guys kill themselves in the end ( Happpens in both, and the hero gets away with everything!). There are lots of twists and loads of characters in both movies!!
It's obviously not a complete rip-off!! I loved kaminey for its awesomeness, though the similarities are uncanny!! Its more like a bollywood version of the movie, but done right!!
Who else is with me on this?? And ya it's just an opinion!! I loved the movie too, so fanboys don't jump on me :P
