Cameron's long been linked to a Spider-Man movie. Spider-Man would make a terrific film. Just go for it realistically. That should definitely. Yeah, I would like to see that happen.
Costs are everything.
Same thing with Virus. The reason they made Virus is that it had to be made for a price. As a film-maker, you start to get nervous because you're not making a film now, you're making a product that has to deliver. Which makes you start to think. A sequence you might have had regardless of the cost and that was integral to the movie.
