My conclusion is that Linney is Diane's mother, and Wally is her father. The others in the room are silent family members. Linney says that she was once married to Wally for ten years. Twice she takes hold of Betty's hand. Woody (the abusing phallus) is "Dad's best friend" and he hugs Wally at the end of the scene after Betty leaves the room. Wally and Linney's careers symbolize parental roles — producer and casting director. — sinbad555
Did anyone notice that Wally starts off his introduction of Betty to the group with the word "voilà". He is one more character alongside Aunt Ruth and the magician who is linked to the French language in MD. — spaghetti-sauce
A possible reference to this Mr. Brown, holding a Winkie's cup? He certainly can get his movies made.
