in the announcements, not through the additional perspective of the later, more developed work.
In the instant case, the only “copyrightable elements” in the publicity materials (albeit injected into the public domain, rather than registered for copyright) are even more limited than in Siegel. While the promotional announcements in Siegel at least showed proto-Superman holding a car over his head, establishing a distinguishing characteristic of “extraordinary strength,” the publicity materials here reveal nothing of each film character’s signature traits or mannerisms. At most, the publicity materials could have injected some of the purely visual characteristics of each film character into the public domain, akin to the character in “a black and white leotard and cape.” Id.
