Funny that you mention the dog the dog is named after the Astors they used to own so much property in Manhattan and it’s a playoff their name I didn’t know that I just read a book about them and they had that in there as one of the fun facts about them
Because I read a book about the Vanderbilt and then I read a book about the Astros both very interesting since they were both started about the same time one was old money and one was new money but it was a very interesting and the dog from the thin man is a playoff the name Astors
But I do enjoy those movies they are really funny
