Several outfits and props are from the original book illustrations and catalogs, such as Samantha's nightgown and pink talent show dress, and the doll with a nutcracker (panned over near the end.)
The book that Aunt Cornelia gave Samantha when she met her was "The Wizard of Oz". The actress who played Aunt Cornelia (Rebecca Mader) would go on to play Zelena /The wicked witch in a "wizard of Oz" storyline on "Once Opon A Time"
Hannah Endicott-Douglas plays Nellie's younger sister Bridget, although she is actually 6 months older than Kelsey Lewis who plays Nellie.
Kelsey Lewis is a brunette, but dyed her hair red for her role of Nellie.
