Mysterio is set to make his big-screen debut next week, but he might have appeared earlier.

Sam Raimis Tobey Maguire-starringSpider-Manseries wasnt always intended to finish where it did.

But when has the fact that a film doesnt exist ever stopped us geeks from talking about it?

Our curiosity is always too strong, andSpider-Man 4 one of the biggest what could have been?

moments in comic-book movie history is no exception to that.

Spider-Man 3reached theaters in May 2007.

By October 2008,Sam Raimiwas talking publicly aboutSpider-Man 4.

It would be a real endurance test, Raimi admitted.

Probably only Peter Jackson knows how hard something like that would be.

He said that right now were just working on the story forSpider-Man 4,just that one film.

Im hoping shell be in it and Im planning on having a story with her in it.

Bruce Campbell having made brief cameo appearances in the previous films was believed to be returning.

I promised him a good, meaty role.

But his character died in the last one; same with Uncle Ben.

I cant let them go, in each and every picture; but it gets harder and harder.

Behind the scenes, there were rumors that the firstSpider-Manfilms writer David Koepp was eyeing a return.

But instead,Zodiacs James Vanderbilt got the job of scriptingSpider-Man 4.

So, the original Spidey screenwriter didnt come back and Dunst didnt look like a sure thing.

Were hoping its not too far down the line!

he toldIGNabout Curt Connors cinematic evil turn.

Ill be trying to get on the Lizard costume when Im 80.

But its like these great characters, that are there in the comic books.

And its like, just open that door up; Im ready to go!

Thats just me talking.

In fact, lots of other villains seemed to be in contention.

Perhaps this was an attempt to ensure that Felicia didnt feel too much like a Catwoman copycat.

So, we know at least that Felicia Hardy would have been in the movie.

Then what happened?

Although the road had been quite bumpy, then,Spider-Man 4had gotten pretty close to being made.

So then what happened?

This means that Raimi and the cast including star Tobey Maguire are out.

Beyond the films themselves, I have formed some deep and lasting friendships.

I am excited to see the next chapter unfold in this incredible story.

In March 2013,Vultureasked Raimi to comment on his departure from the Spidey franchise.

Go ahead with your reboot, which youve been planning anyway.

And [former Sony co-chairman] Amy Pascal said, Thank you.

Thank you for not wasting the studios money, and I appreciate your candour.

It all sounds quite respectful, then, with Raimi making the decision to put quality above all else.

Deadlinereported that Raimi hated theSpider-Man 4scripts, but the director has never said anything like that on the record.

His last word on Spider-Man was to tellHey U Guysthat he loved Marc Webbs new take.

Raimi and Maguire have found plenty of work since, as well.

But its always fun to wonder what Raimi and friends would have done with them.

Spider-Man: Far From Homeopens on July 2.
