What do you consider the first "modern" superhero movie?

They really didn't show that the characters could carry their own movie, though. Howard was a flop, costing more then Return of the Jedi to make. And Nick Fury was unsuccessful as a pilot, and came the same year Blade was out. Blade on the other hand, that movie showed that a obscure character can hold their own movie.

And neither of the two are among the earliest superhero movies, just Howard there is over 30 titles, movies and serials included that precedes that movie. And Nick Fury the number have at least doubled, so as a whole both movies in general is pretty late Superhero titles.

That we got Ant-Man and Guardians of the Galaxy is because Marvel Studios don't have X-Men and Spider-Man (hence why we're getting Inhumans as possible Mutant analogues).
