What is the difference between Spider-Man and The Amazing Spider-Man movies
I would like a bit of history here, meaning I would like to know the difference in terms of creator, producers (or publishers of the comic if needed to explain the differences) and some explanation around the need of having two types of Spider-Man series (if it is for example a different producer, or Stan Lee didn't like one of the two or something like that).
I am particularly interested in the movie franchise where the two movie franchises almost overlapped each other.
Please clarify if you're more interested in the movies or the comics. There are multiple Spider-Man comics, including one simply called "Spider-Man" and one called "The Amazing Spider-Man". They are generally the basis, but not the same continuities as the "*Spider-Man*" and "*The Amazing Spider-Man*" movie series. You mention the movies, but also the creators/publishers.
Possible dupe, very much related: Why do different actors play different versions of Spider-Man?
@phantom42 I think it is quite clear what I am more interested in when I say "I am particularly interest in", isn't it?
There was very significant overlap between the cast/crew/production teams; http://www.imdb.com/search/name?roles=tt0948470,tt0145487
The Amazing Spider-Man is the name of the mainstream first spider-man series, set on in the main Marvel shared (with other comics such as the main X-Men, Incredible Hulk, Fantastic Four comics) universe that started in 1963 and is still going on with multiple releases in a month. I'm guessing the reason it's called Amazing is due to Spider-Man originally appearing in Amazing Fantasy before getting his own series.
That's where the new movie series got the adjective from. The reason they choose it is to distinguish themselves from the previous trilogy. I don't think it's meant to indicate that the movies aim to more closely follow the storyline of the main comic. For one thing the director of the new movies said
It's less based in Steve Ditko world and probably closer visually and more influenced by "Ultimate Spider-Man" but it is also very much a world of our own devising."
(Ultimate Spider-Man is an alternative comic line and continuity, modernized and meant to be more accessible to readers not familiar with 50 years of back story)
The reason for making a new Spider-Man movie universe so soon is financial probably because they made tons of money on the previous films, they also seem to be planning spin-off movies based on Spiderman Villains), I've fairly sure I've heard rumours in the past that Sony looses the rights to Spider-Man if they don't make enough movies but I can't find any credible statement or rumor about that right now. The reason they didn't continue with the previous trilogy was due to disagreements with the producer Sam Raimi.
I remember hearing that if they didn't make a movie they would lose the rights as well, I believe during a Toby McGuire interview (either Letterman or Leno) when Toby was talking about why he was dropping out of the movie. I believe Toby backing out is really why they made so many changes, as I am fairly certain the original plan was just to make a Spiderman 4.
