Which was never true, at least episodic salaries. She got in the £100k range per episode (which was huge back then and still is today of course), but at the same time nowhere near producing a pilot. With that said, since Melrose pulling out 32-34 episodes per season that was still 3-4 million per season to Heather alone.
The Terms of Endearment theme over that Jeremy & Erica scene ... It's a bit of music that made the daytime rounds. CBS used it to promote the soaps during its 1984-85 affiliate reel. Anyway, I wonder if it was just for the promo or used in the actual episode.
