The whole idea with Liz Allen and Doc Ock as the villain wasn't from Cameron. When Cameron was suppose to do X-Men with Chris Claremont, James Cameron left in favor to do Spider-Man because Stan Lee offered it to him. I think Caroclo had the rights at the time, they pretty much wrote their own little script and credited Cameron as a writer, I although he had nothing to do with it. I mean, this is the same guy who did Terminator 2 and Aliens. I'm assuming that eventually, he realized that the script was a giant piece of ****, so he wrote his own "scriptment" with Electro and Sandman as the villains. A better movie, but back then...it could've been a masterpiece for the 90's.
Tell me more about that book. Do they talk about Cameron's movie? It sounds exactly like what the writers wrote for it.
