As much as we all may like to think we know these Hollywood figures, the truth is we don't. For every interview or anecdote about Cameron being a complete nightmare to work with, there are just as many people who have said nothing but great things about working for him, and it shows...Arnold Schwarzenegger, Bill Paxton, Michael Biehn, Linda Hamilton, Sigourney Weaver, etc. have all worked with him on multiple occasions and not because they thought he was an unreasonable jerk. Even Kate Winslet, who had an infamously strenuous relationship with him has gone on record saying she enjoyed working with him and wouldn't trade it for anything. There's a difference between wanting everything to be perfect and being an unreasonable tyrant. If he was as bad as some people are making him out to be, Disney wouldn't bother going forward with the project, and certainly not spend the billions they did to get the chance to use his property that they surely knew he'd be protective over.
