Margaret speaks Irish Gaelic to Emily while she's in the hospital. But couldn't seem to understand it when she was being spoken to by her younger sister in episode Peg of Old.
The episode won an Emmy Award for Outstanding Art Direction for a Single-Camera Series.
The dollhouse in Emily's room is The Beacon Hill by Greenleaf. It is a modern house, not from the 1920s.
Except for his towering height, actor Glenn Fleshler who plays George Remus could be the real Al Capone's double.
