That could be quite profitable (probably a TV series or comic), but is he family friendly enough?
Of course he is.
This is very interesting news considering the links to Universal.
I wonder if he is going to let some Imagineers have a look through those file cabinets. Its more about the ideas then the man himself, at least how I look at it. Something that wouldn't really work as a comic could be great as a theme park attraction, and vice versa of course.
As for the rights, its a huge mess ... but basically it goes like this.
Mr. Lee himself held the rights to the 'major' characters until 1998, when he sold them to 'Stan Lee Media' in November 1998. Then appearantly he sold the rights again a month later to Marvel. Or so Stan Lee Media says.
Mr. Lee left Marvel in around 2002, and then sued Marvel because he was not receiving enough compensation. I don't remember what happened with that lawsuit.
Earlier this year, Stan Lee Media sued Marvel for $5b saying they were using the characters without Stan Lee Media's authorization. Mr. Lee defended Marvel, saying the lawsuit was baseless.
I believe that Marvel is considered to be 'in the right' and the legal holder of the rights to Spidey, Hulk, etc.
