Sorry to burst YOUR bubble, but not all works are under copyright.
Specifically, works released into Public Domain, and works on which copyright has expired (like all the stuff Disney is ripping off).

While works are protected under copyright laws automatically, they receive stronger protection if there is a copyright notice, and even better if they are registered with the US Copyright Office.
