Lillian Gish's credits go back to 1912 and run through THE WHALES OF AUGUST in 1987. And, unlike Gloria Stuart, she worked sporadically in films through the decades in between.
It would be nice if they could use Gloria Stuart's audio commentary from the old laserdisc. James Curtis, the author of "James Whale: A New World of Gods and Monsters" once told me that it was this commentary track that got her the role of "Old Rose" in "Titanic".
