You're thinking of "I (heart) Huckabees", which was a pretty kickass movie but focuses more on the existential/nihlist distinction. Man I remember watching that movie for the first time blazed out of my mind. That was an experience.

As for hinduism, it's remarkably poetic and I love the symbolism that goes into it. As has been said there's a strong sense that all are simply manifestations of the universal One. If you really want to know more about it I'd suggest reading something like the Bhagavad Gita.
