The pitch was to use the original actors, then Harold Remis died, then Weaver agreed to do it but only if her SON in the 2nd movie was one of the replacements, then she decommited. At this point, they could not have gotten studio support without some gimmick that will grab attention. Those are the facts, but i find it amusing and *regressive* that you have no similar rage against the original ghostbusters for intentionally excluding female, gay, asian, or hispanic leads
Your conjecture is just biased ranting. There have been ZERO gay, hispanic, or asian characters in the top 200 grossing sci fi and action movies. In fact, any gay theme will almost always get an R rating. Where's your rage about that? Clearly your contempt for "liberal" hollywood is just wildly inaccurate. The truth is that studios go for profit, that's it. As the hacked sony emails proved, they will defer to racist viewers in asia every time over giving a talented black actor like denzel washington a leading role.
The only speck of truth in your accusation is the "token black" character, which has been around since the 1st ghosbusters or longer, but where you're dead wrong is assuming this doesn't annoy most liberals too. It's so forced and distracting, and most of those characters are worthless - like winston zeddmore
And btw, the last thing hollywood would do with ghostbusters 2016 even with your desired all white all male all hetero cast is make a "good movie with good actors and good stories." They just don't do that any more, and this is why they could not get bill murray on board
