Oh my gosh... I finally have my answer after all these years as to whether or not Cameron was forewarned! And it turns out he was. Wayne, Harlan would be very pleased to know this, I'm sure. Yes, Mr. Ellison fiercely guards his work and has threatened many a party with a lawsuit in the past. He can be most irascible and suffers fools not at all, but there is a playful, boyish side to him as well. As a child of short stature he was often mercilessly teased and wailed on alot and he compensated for this over the years by cutting people down with words. He has fired barbs at actors, producers and the like and his volatility and acerbic wit is legion. He makes for a very interesting character study as he so often rails against the very forms of media entertainment that have made him a great deal of money (television and the film industry). As I heard it once, Harlan was pitching his idea for the original Star Trek movie when a producer, liking what he heard suggested the inclusion of Mayan warriors. When told there were no Mayans in the time period in question, the producer insisted all the more, prompting Mr. Ellison to hurl himself down a boardroom table in a vain attempt to strangle the person! And needless to say, he would not go on to write the screenplay to the first or any Star Trek films. I've often wondered what additional superlative teleplays in the field of science fiction we might have been witness to if Harlan Ellison had been given a freer rein. "City on the Edge of Forever", "Demon With a Glass Hand", "Paladin of the Lost Hour" and many others--they are all absolute standouts for drama.
