I am quite amused that that awful film might come to some good purpose. At least for my entertainment, if not to the ERB Estate.The Betty Boop case that was decided last year -- Fleischer Studios sued a manufacturer that was creating Betty Boop merchandise based on the public domain cartoons on the grounds that they were violating the Betty Boop trademark -- would have some application here as the court held that trademark doesn't trump copyright because if it did then nothing would ever enter the public domain.I love how ERB Inc. is complaining about the "risque" nature of Dynamite's material. Have they not read their founding father's books?
Other than that, it does seem like a clear-cut case of trademark infringement, though.
Dynamite can also argue trademark abandonment because ERB didn't sue to stop production or release of the Asylum adaptation of A Princess of Mars.
