Artist Dan Paulos was so inspired by Rosemary Harris in The Holocaust that he created a piece of artwork featuring her. He recounts how he met her and came to work with her on a short film.
Naturally this piece is mostly about Jennifer Ehle's mother, though there is some mention of her. Moreoever, it's a fascinating story.
TheaterMania also has a long Rosemary Harris interview from 2000, in which she speaks lovingly and proudly about her daughter.
