Trust me, Ron, Sorbo and his manager were in script meetings that I WASN'T present in. I was just presented with a bunch of changes I suspect were designed to throw me off the script. I got the whole truth from the very topline exec at Universal at the time who was overseeing the film. Many of those actor ego "concerns" about the script were placated.
And, yes, in many quarters the writer got blamed. But thanks to a very smart PR blitz I did (I was one of the first writers I think to hire a PR man...which has now become de rigeur for many writers), the truth came out in many genre magazines and articles. That's why Sorbo sent me the letter; I had earlier beaten Raffaella at that game when I hired a PR person to handle my publicity on Dragonheart, which caused a big furor, including a huge article in the LA TIMES.
Sorbo, probably at the behest of Raffaella, was trying to butter me up to keep me quiet during KULL. Of course, KULL came and went so fast, there wasn't a need to do as much self-defense PR on it as there had been on Dragonheart. I ended up in Cinefantastic being mentioned in the 50 most important stars of Sci-fi/Fantasy as a star on the rise, saying essentially I wrote really great stuff but didn't have the clout to keep it from getting destroyed. Raffaella ended up in the star descending section, mentioning I believe her desecrations of my two scripts.
The whole fracas is what eventually got me elected to the WGA Board where I ran on one issue...Creative Rights.
