Books, Films, TV shows and other media relating to cloning?

Gattaca

Good movie about a society that consists of an genetically optimised elite and some "naturally created" social underclass.

There is a book in which a cloned sibling is used as a "organ bank" for the "true 1st born". Life of my sister? Something like that.

Definitely this. Gattaca is a must-see movie IMHO for everyone.

Also you can look into TED lectures if you want. I am quite sure you'll find something about it.
