Creation and casting
According to Shelley Long, Diane looks more intelligent than she really is. She uses books and academics to communicate with others, usually unsuccessfully. After a series of events which bring her scorn and ridicule, Diane realizes that she knows little about the real world and the bar, and must learn about the world without using books.
Wendie Malick auditioned for the role of Diane; she later appeared in Frasier as Ronny Lawrence.Bess Armstrong was offered a role, but she turned it down. Long, Lisa Eichhorn, and Julia Duffy were the producers' top three considerations for the role.NBC executives praised test scenes between Long and Danson, so the creators chose Long. Julia Duffy later appeared as one of Diane's friends in "Any Friend of Diane's", a 1982 episode of Cheers.
