Have been meaning to note that Grayson got a one month vacation during this period of DS (I gather that she told them that if Jonathan was getting one, she needed one as well!) Part of the time was spent working on a little known feature film, Adam at 6 A. M. Below I've pasted in the review of the movie I wrote for IMDB. Even though Grayson's scenes are few and far between, it's worth seeing her in action here.

The hard life of Mikey Douglas--an early chapter
This is a very early Michael (or as he was popularly known then, Mikey) Douglas vehicle. He plays a disillusioned college professor of the late Sixties (there seem to have been so many of them scurrying about in those days!) who drops out of his successful, stressful life in the big city to go in a search for his roots in a not-so-idyllic midwestern small town. The story plods along, showing his courtship of a rather status-proud Junior Miss type whose Mom (wonderfully etched by Louise Latham) is the town hairdresser, and his adventures in serious male bonding with Joe Don Baker and other flannel clad logger types. Grayson Hall has an excellent cameo role as his aunt, and gets to administer a deft put-down of Douglas' masculine vanity towards the end. In some ways the last 30 seconds is the best part of the movie. Overall not at all a bad effort. To quote Maggie Smith in a movie that is much more suitable to this writer's temperament, "For those who like that sort of thing, that is the sort of thing that they like." I did make liberal use of the fast forward button in viewing "Adam at Six A. M."
