If you have any interviews, quotes, or statements that contradict his story I would love to read them. Pretty much everything I can find from Lorraine Williams directly is about Buck Rogers, not D&D.
I think you might have missed the point of my comment.
But sure, I totally believe that this guy was constantly thwarted in his ambitions by some "lady" who knew nothing, because he totally knew James Cameron and Francis Coppola who completely wanted to make a movie with him. Except the "lady" (remember, licensing Buck Rogers, brother wrote screenplays in Hollywood) had no idea who people like James Cameron were and didn't prepare for the meeting. The same James Cameron who, the year before had released T2. So this guy had to school the lady.
Sounds plausible.
