Can we all just agree to hold off the sark until AFTER we start getting posters and trailers, please? If there's one thing James Cameron has going for him is that he's a master of proving people wrong. Hell, he's made an entire career out of it! Allow me to reenact:
Studio exec: "Hey, aren't you that James Cameron fellow who did that crappy Piranha 2 movie?"
James Cameron: "They screwed me over on it, plus it wasn't really my movie or idea."
Exec: "*Sigh* FINE. What do ya got for us?"
Cameron: "I'm gonna make a sci-fi action thriller about an evil robotic assassin from the future who comes back in time to assassinate a woman who's unborn son would lead humanity to defeat the machine uprising it serves. And it'll star Arnold Schwarzenegger. "
Exec: "Oooh! That guy from Conan the Barbarian! That was a huge hit!"
Cameron: "As the titular evil robot."
Exec: "WHAT?! You fool, that'll never work!"
*One movie later*
Cameron: "It worked."
Exec: Alright, then. What's next?"
Cameron: "Well, now I'm gonna direct a sequel to Ridley Scott's "Alien", but it'll be more action-horror, with more than one alien and it'll turn Sigourney Weaver's character into an iconic bad-ass action hero by the end!"
Exec: "You fool, that has box office failure written all over it!"
*Another movie later*
Cameron: "The sphincter says what?"
Exec: "I stand corrected. What next?"
*Several similar back-and-forths later in 1997*
Exec: "Well, Jim, my boy, you've made us a ton of money this past 10 or so years. What exciting sci-fi or action concept do you have for us now?"
Cameron: "I have something, but it's not sci-fi or action."
Exec: "WHAAAAAAAAAAT!?!?"
Cameron: "Yep, it's a historical disaster-drama set aboard the Titanic centered on a fictional Romeo And Juliet-style romance. It'll be massively big-budgeted and star those two up-and-comers Leonardo DiCaprio and Kate Winslet, and I plan to have it win Best Picture at the Oscars and become the highest-grossing movie of all time!"
Exec: ".........ARE YOU OUT OF YOUR DAMN MIND?!? NOBODY'S gonna wanna see this! It sounds like an actual disaster waiting to happen!"
*One movie later*
Exec: "Holy ****.....it worked. Your movie did everything it said it would, Jim. What do you plan on doing next?"
Cameron: "I'm gonna spend the next decade planning my dream project: a sci-fi epic set on an alien planet who's story will have a bit of an pro-enviromentalist message to it without coming off too cheesy (that's what Pocahontas got wrong) and will make breakthroughs in CGI and motion-capture technology as well as make 3D popular again! AND I plan on breaking my own box office record, inevitably lose it again a decade later, and then have my same movie REGAIN it thanks to an overseas re-release two years later. And by THAT point, I'll have been actively working on multiple sequels to it!"
Exec: *Raises a glass with a smile on his face* "Shine on, you crazy diamond."
