What films makes us think about our existence?

Not exactly existentialist movies, but movies that actually make you think "what are we?" what is our purpose of living. because some films can also be described existentialist because they focus on the condition of human life. that's not what i'm searching for because it doesn't interest me. what films actually ponder on the meaning of our existence and the meaning of our life? So more in the philosophical sense of the word existentialism and less of the social meaning. I reposted this because i wanted to put it in another category.
