Om Shanti Om — Addendum
Don't know if there's anything to this but I found it interesting that Om Prakash was only able to achieve his goal of reaching a new level of society, a new class, through reincarnation. He had to be reborn into the upper strata. Hollywood films usually allow class-jumping to occur in a single lifetime. The original moguls of Hollywood, with their lower-class, eastern European origins, certainly understood this dynamic.
Also, when the villain, Mukesh Mehra, recognized the reincarnated Om as the original Om, and laughed because he knew Om's evidence, based upon his reincarnation, would never stand in a court of law, Om should've laughed back and said, “Don't you get it? I'm reincarnated. That means you're going to be reincarnated, too. And, given the way you've lived your life, what will you be reincarnated into? I don't care about the courts here but you should certainly care about the courts there.” Might've turned the movie into more than a reincarnation-revenge flick.
