Earlier quoted context omitted.
For something like a movie they mostly consist of a hash list which is clearly a derivative work based on the original so probably. http://en.wikipedia.org/wiki/Torrent_file EX: A 4GB file using 4MB pieces would have 1000pieces x 20 byte hashes or 20k of 100% derivative work. And ~2k for all other meta data.
By your logic a plot summary would be a derivative work. You can't recreate a movie from a plot summary, same way you can't recreate a movie from a torrent file.
PS: If you created a random file that happened to contain a movie's hash your free and clear. If you keep generating random files and comparing them to a movie until you get the one you want your not free and clear. Same bit's, different process different result.
