First of all, Johnny Depps unfathomable awesomeness aside, it was Gore's vision that made Black Pearl such a great movie for anyone inside (and outside) the disney market. I dont blame him for passing on number four, and even less for the intellectual property Bioshock!
This was the best game I played over Christmas 07, and its got everything you need for a movie. An epic setting, think Ayn Rand with some Orwell thrown in, with a really messed up populace, and then Verbinskis classic visuals are kind of tailor made for this film. Just dont fuck up the casting!! (Andrew Ryan - Alan rickman? can he grow a good moustache? I vote Ciaran Hinds, and maybe Kevin McKidd for Fontaine)
