Horizon Comics Prods., Inc. v. Marvel Entertainment, LLC, No. 15-cv-11684 (D. Mass. filed Apr. 23, 2015): Newly filed; the claim is that movie Iron Man’s armor infringes the copyright in another comic armored suit.  All I’ll say right now is that one part of the allegations is clearly silly: the complaint alleges that one movie poster is a copy of an image from plaintiffs’ cartoon:

Three Point Landing is such a trope that it has its own supercut, as well as its own entry on TVTropes.  (Warning: link goes to TVTropes.  I accept no responsibility for the time you’ll spend there.)  I would kind of love to put together the exhibits for the motion to dismiss, actually.
