Debra Granik talked about the evolution of the female character:
"As a kid, I got really envious of men's coming of age in movies. Their knowledge of darkness would grow, their compassion would grow, whatever it was, it felt like they would gain something, and the female coming of age often was punitive, like an unwanted pregnancy. We're all like, 'Oh God, I'm so glad I'm not her.'"
"People are finding these heroines charismatic, unexpected and fresh," Granik says. "What a person in the business can get from that is, 'Hey, a young female protagonist doesn't need to have a boyfriend, get pregnant, cut herself or be naked to attract an audience.' "
Nine-year-old Pippi is unconventional, assertive, and has superhuman strength, being able to lift her horse one-handed without difficulty. She frequently mocks and dupes adults she encounters, an attitude likely to appeal to young readers; however, Pippi usually reserves her worst behavior for the most pompous and condescending of adults. She turns white around the nose whenever she gets angry, though this rarely happens. Pippi's anger is reserved for the most extreme cases, such as when a man ill-treats his horse.
