Just watched a BBC doc by Jonathan Ross called In Search of Steve Ditko. For people who don't know much about Ditko, it's a pretty good and thorough summary of his work; for people who do, it's a star-studded retrospective featuring thoughts from Alan Moore, Neil Gaiman, Mark Millar, Joe Quesada (in the halcyon days of 2007 when you could mention his name and Spider-Man's in the same sentence without a string of profanity), Jerry Robinson, John Romita, and, most illuminatingly, Stan Lee.
Stan comes across as largely sympathetic, and it's something of a vindication of him. He praises Ditko's work effusively, and acknowledges that by the end of Ditko's run, all he (Lee) was doing was adding in dialogue balloons. It's sad to think that decades of bad blood boil down to nitpicking over the definition of "creator". While I agree with Ditko's definition and don't believe Stan pitching an idea is enough to count as "creating" the character (I also think of Bill Finger as the primary creator of Batman), Stan's the one who's been a standup guy about it in recent years -- even though he clearly doesn't buy the "co-creator" moniker himself, he's made sure it's put on every Spidey comic, movie, cartoon, and game simply because he knows it's important to Steve. (Or so the unfortunately-named Ralph Macchio claims; this could just be another example of Lee claiming credit for something somebody else did.) He even sent him a signed letter in '99 saying he has always considered him the co-creator, but of course Ditko objected to that choice of words; if there's one thing an Objectivist hates, it's subjectivity.
[spoiler]In the end, Ross and Gaiman track Ditko down. They get to meet him, but, characteristically, he refuses to allow the camera crew in, and Ross reveals nothing of their conversation except that Ditko is pleased that there are people who appreciate his work so deeply.[/spoiler] It's an interesting contradiction -- the recluse who wants to be left alone but also wants recognition. We never do hear Steve's explanation of why he left Marvel, but we get a pretty good feel for him as a person.
Other interesting things of note: the live-action Spider-Man TV series (I'd heard of it but wasn't actually sure it was real) and the 1970's Doctor Strange pilot. Both seem like good picks for Outer Heaven if anyone can find them.
All in all, highly recommended. There's no DVD release (at least not in the US), but it's not hard to find a torrent. Check it out; you'll be glad you did.
