Mary Astor - Always a Mother
Poor Mary Astor - why was she given all these mother roles at such a young age? She was only 30 in this movie, playing the mother of a 13 year old girl! She's an attractive woman and does well as a leading lady (like in Dodsworth and The Great Lie). But she often got stuck in these "mother" roles.
For instance, she was 11 years older than Lucille Bremer, who played her daughter in Meet Me in St. Louis and 16 years older than Judy Garland. And she played Judy's mother in three movies!
