Comic book movies, like those in the Marvel Cinematic Universe, are far more popular than the comics from which they originate. Indeed, some of that even goes back to early TV series like the Bill Bixby Incredible Hulk or Adam West’s Batman, which served as the faces for those heroes to the public well outside the comic demographics. In spite of this, though, almost everyone going to see Iron Man or Wonder Woman in theaters knows that they’re characters from comic books.
Then there are other movies, where few people even know it was originally adapted from another medium at all. The success of the film so totally eclipsed the source material that it’s almost completely unknown in comparison. And that’s where we find these, four films that have left the sources to languish in the shadows of their popularity.
