The on-screen credit for Stan Lee, Don Heck, Larry Lieber and Jack Kirby reads: "Based on the Marvel Comic Book By". The profile for my copy of 'Iron Man' has these entered as original characters by, while I would have expected "Based on the Marvel Comic Book By" to result in an original material by credit. Checking the various entries in the database using the CLT, I find that about half of the 'Iron Man' profiles uses OMB for this, while the other half uses OCB...

So, just to be sure: what should it be?

I would go for Original characters by because it's matching so good into the notes from the credit chart  :

Quote:
Used for screenplays based on characters from another work, credit the author of the characters here. For example comic adaptations and sequels.

But OMB sounds also not wrong, because, like you said, it's based on the comic book by ..., so it's adapted from another medium.

I dont't think in cases like this, the bound can be drawn this exact.

This is the reason I always use OCB for comic adaptations.  While I can see it being argued the other way, I have a hard time going against the example given in the rules.

Agreed.  The origin from Tales of Suspense 39 is very close to what's in the movie (updating to a more recent war, of course).

It's not just based on one story though. Which is weird because that fact doesn't really help either arguement in any way. The character of Iron Monger, who appears in the movie, didn't appear in the comics until much much later in Iron Man's run (first time in armor I believe was issue #200).

So it's not specifically based on one original source material by all the above mentioned people, but it is based on the character created by them.

Iron Man was created by the above mentioned, which supports the original character by arguement, the origin is similar, which supports the original material by. Extra stories and characters were added in (such as Iron Monger, created by writer Dennis O'Neill), Pepper Potts (created by Stan Lee as well, but also Robert Bernstein) and James Rhodes (created by Bob Layton, Sr., David Michelinie & John Byrne).

So with all those characters added in but none of the creators getting a credit, a credit or original material by seems to fit, but considering it's not based on just one story, original characters by seems to fit as well. I'm just confusing myself. 

The original credit in the film doesn't really help either, as it could obviously mean both for the purposes of DVDProfiler.

I personally don't think it's specific enough to point out one story as the original source material, it points out the whole comic run basically, which has hundreds of writers and artists, so I voted for OCB.
