Ooh, ooh I got this one. Identifying and acquiring compelling public domain motion picture works and then creating copyright-eligible derivative works is my full-time job. A derivative work is a work based on or derived from one or more already existing works. Common examples include translations, musical arrangements, motion picture versions of literary material or plays, art reproductions, abridgments, and condensations of preexisting works. Another common type of derivative work is a “new edition” of a preexisting work in which the editorial revisions, annotations, elaborations, or other modifications represent, as a whole, an original work. To be copyrightable, a derivative work must incorporate some or all of a preexisting “work” and add new original copyright-eligible authorship to that work. The copyright in a derivative work covers ONLY the additions, changes, or other new material appearing for the first time in the work. Protection does not extend to any preexisting material, that is, previously published or previously registered works or works in the public domain or owned by a third party. As a result, it is not possible to extend the length of protection for a copyrighted work by creating a derivative work. A work that is, or has fallen into the public domain, that is, a work that was never or is no longer protected by copyright, is also an underlying “work” from which derivative authorship may be added, but the copyright in the derivative work will not extend to the public domain material, and the use of the public domain material in a derivative work will not prevent anyone else from using the same public domain work for another derivative work.
