Duke University's Center for the Study of the Public Domain has created a comic book on copyright. It is called Bound by Law and features the issues surrounding film-making and copyright. It is both entertaining and very informative.

It is a free download in digital version, or a hard-copy version is available for purchase. The comic can be remixed for your own use by downloading individual pages, or you can read it a page at a time (including turning the pages with your mouse), or download the text so you can translate it into another language.
More comics are planned.
