Romeo and Juliet EVERYWHERE?!

One of the places I can remember something about Romeo and Juliet is in West Side Story. It has the same portrayal of two star-crossed lovers, but I don't remember if they take their life. But both households are alike in dignity, where they spill civil blood which makes their civil hands unclean. Where the lovers take their life because of a long lasting grudge, that ends in the two having to make up.
