When talking about turning The Amazing Spider-Man franchise into its own movie universe, Tolmach commented:

That’s the new thing that we constructed. We brought in [Alex] Kurtzman and [Bob] Orci and [Jeff] Pinkner on this last movie as the writers and we fell in love with that dynamic. We were all so enamored of the script they wrote, and just the spirit of the collaboration, that we decided that there are all these other stories to tell: not just Spider-Man movies but the ones that we’ve announced, The Sinister Six and Venom, and they all come from the same place. We realized it would be really good in terms of storytelling to have a grand scheme for where and how these stories grow out of the centerpiece, which is always Spider-Man…

The most exciting stuff deals with the question on everybody’s mind regarding these villain-centric flicks: how true to character can Venom and The Sinister Six be if they’re the protagonists of their respective movies?

It’s a challenge in every sense. Obviously questions of traditional hero/villain dynamics have to be looked at. At the same time it’s an awesome challenge, because some of the greatest characters are in fact villains, and how you construct that is so much fun. People love those bad characters if they’re good bad characters, and love to watch them. And nobody’s all good, nobody’s all bad…

Avi Arad contined to comment on a Venom movie.

Venom hated only one guy – Spider-Man. He wasn’t innately bad, he was a shortcut guy, not really into fighting hard for achievement. That’s the Venom story. Can he also be a good guy? As you know, Venom was also called ‘lethal defender of the innocent’. We had a great history with him, especially caring for the homeless, which is a very sensitive issue and something that many of us are very concerned with. Our villains all represent a different side of the misunderstood, and some of them unfortunately turned to the dark side. Venom happened to be a phenomenal character.
