I don't know if anyone is interested but since we're on the topic of a draft written by an early writer on Spider-man 2, I listened to a podcast where Gough and Millar spoke at Southern Cal, and they claim much of the finished film was their work.
They said they pitched largely what the movie ended up being: MJ successful and engaged to John Jameson; Doc Ock having a wife, the inhibitor chip plot device, and his redemption arc; and Peter losing his powers because of streess. They seem a little peeved that they didn't share a screenplay credit with Alvin Sargent.
