Spidey 3 - Bollywood influenced?

i wonder what sam raimi did with the song and dance routine? maybe kirsten dunst and toby maguire were singing and dancing around the web and the web gave way...

other than the song and dance routine and the fx, its very much takes off on orthodox bollywood themes.. love between friends, two friends after the same girl, evil avatar of the good hero (though bollywood would have made this as the evil twin of the hero and the twin too would have been after the girl), and lastly, sacrifice of the friend in the end..

if bollywood was able to copyright its themes it would have made a killing on spidey
