I was recently reading the article Films considered the greatest ever on Wikipedia. Being a fan of Korean movies (of course I have watched only 4!), I got hold of the movie `Old Boy'. And in the midway of watching it, I realized that Bollywood has a remake in the name of Zinda.
Wikipedia `Zinda' entry says:
Most reviewers considered it to be a rip-off of the South Korean film Oldboy. Show East, the producers of Oldboy, initially expressed concerns but took no legal action as the studio had shut down.
Looks like these guys haven't paid for the rights, damn you. And you talk about piracy.
