 The show's premise and major aspects of the main character—including being cut off financially from her parents, becoming a writer and making unfortunate decisions—were drawn from Dunham's own life.
 Apatow said he was drawn to Dunham's imagination after watching her independent feature film "Tiny Furniture" (2010), and added that "Girls" would provide men with an insight into "realistic females".
The Fox sisters were three sisters from New York who played an important role in the creation of Spiritualism: Leah (1831–1890), Margaret (also called Maggie) (1833–1893) and Kate (also called Catherine) Fox (1837–1892).
 The two younger sisters used "rappings" to convince their much older sister and others that they were communicating with spirits.

 They all enjoyed success as mediums for many years.
