At a panel on Doc Savage, the pulp hero who inspired/was ripped off by the creators of Superman and Batman, among other creators of your favorite Golden Age comic book superheroes, long-time superhero movie producer Michael Uslan (who is also producing the upcoming Captain Marvel film) let slip that a new Doc Savage film adaptation is in the works.
I recently read panelist Anthony Tollin's reprints of some Man of Bronze adventures—for those who don't know, the moniker refers to Savage's awesome tan—and while I wasn't blown away by it as pop literature, I did see some obvious seeds of Superman, including the snow-bound Fortress of Solitude.
So here's hoping the new Doc Savage movie is an improvement on the first one, Doc Savage: Man of Bronze (1975), and the second one, The Adventures of Buckaroo Banzai Across the Eighth Dimension (1984).
(Joke. Kind of.)
