It's not like his deal with Fox was a big secret, if there was any question on him coming back or not it was whether he wanted to or not, and given how heavily his movie was edited late in production. It looks like someone wasn't happy.
When someone agrees to do two more movies for one studio as the only requisite to come back for a movie of another studio, I'm willing to think that has nothing to do with this someone
almost not coming back because he wasn't satisfied with his prior experience.
We have little to think that he almost didn't come back because of Sony and more to think that he almost didn't because of Fox. He'll be contractually obliged to make two movies for Fox just because he wanted to return and make another Spider-Man movie as soon as possible. That leads us to believe his experience was more positive than it was negative. Anything other than that is just assumption.
I've read it before but the best proof is that they were already storyboarding with the vulture. In order to get to that stage you have to be pretty much complete with the writing process, because you're now trying to visually realize your product. Arad ordered Venom in late in production.
I believe that is done all the time. Like you said, when they try to visualize their ideas, they go with storyboards. Not only that, but also busts, miniatures, drawings, sketches and what have you. That is common, but that isn't evidence that they had a ''greenlight and completed script'', as you said. They could simply be visualizing what they wanted for the story before they started writing. I think there are images of a young Doc Ock that was supposed to date MJ in SM2, but it didn't mean that they wrote an entire script with that idea in mind and that it was already done.
Regardless of that, the final scripts always go through changes midway production. I remember an interview of Jeff Bridges talking about the mess that it was during Iron Man's production, mentioning that they didn't even have a complete script and kept changing it all the time.
That may be common.
And to support my claims that the script was changing even durring filming I have exhibit A:
(This is the original Venom teams up with Sandman scene where Venom threatens his daughter as seen in the novelization)
It's like the case I mentioned above of Iron Man. The final script always goes through changes midway production.
Andrew Garfield mentioned in one of his interviews that TASM is completely different than what he thought it would be when he read the script and that a lot has changed. Watching the commentaries on the Avengers Blu-Ray, Whedon mentioned how, sometimes, an actor would come to him and say ''hey, I don't think my character would do this and say this. Can we try this or that?''
So, like I said before, it might be pretty common. It's not because the script keeps changing that the movie will come out wrong and bad. In IM, it worked. In SM3, it didn't.
In my opinion, at least.
Nice. I don't remember seeing this before. I wish they had kept many of the things they did and others that were rumored to be there.
