Sorry to be so negative, but this article is pure crap. It tells us nothing that we don't already know, and the rest is just fanboy speculation. And just for the record, Willis O'Brian did not sell his King Kong Vs Frankenstein treatment to Toho. O'Brian hired a producer named John Beck to help him pitch his idea to studios. Beck hired a writer to revise his treatment (to KK Vs Prometheus) and sold it to Toho without O'Brian's knowledge. After O'Brian found out that his idea became KK vs Godzilla he was utterly heartbroken and devastated.
I don't know who hires they writers, but I wish at the very least they would do some research to get some knowledge about what they are writing about.
Anyway, enough of my rant
