see selection criteria: theatrical features only; no serials or tv series. it's a different challenge (and arguably easier) to adapt a comic book series into the episodic chapter/based storytelling format of serials and tv, and so not quite comparable. Same thing with adapting them into animated films/series. But they were originally released in theaters, when $.25 would get you the next chapter of the serial, cartoons, coming attractions and a double feature. They kept the kids coming back every week. Just because they're (to use your word) "easier" doesn't mean they aren't valid representatives of the superhero comic-to-cinema theme. They were filmed as complete movies, with the story beginning in episode 1 and continuing to the end of the final episode. They had pretty elaborate sets and special effects for those pre-CGI days. The fact that they were released in weekly segments was exactly how their fans had been introduced to them in the Sunday papers or comic books. It was a natural transition. Not all serials qualify because the heroes weren't super (e.g.- Gene Autry's Radio Ranch, Don Winslow of the Navy. Ace Drummond, and Tim Tyler's Luck) nor did they originate in comic format. But I think a case can be made that the Flash Gordon and Buck Rogers films should qualify. They flew into space to save the world (or universe) from evil. Also- they were later re-released in non-serialized form as complete movies. You might rate them down at the bottom of the list, but they do belong on it as much as the DeLaurentis feature you did include. Later
