Strong Female Literary:
(the first two that came to mind are Laura Ingalls Wilder, Karen von Bixen-Finecke, and Shreve Stockton but they all wrote autobiographies, they weren't in novels!)
Jo March, Little Women
... I know there are more but I'm tired
There are a few in books that are also in movies (LOTR, Pride and Prejudice) that I need to read. I should really re-read The Awakening because I never did make my mind up about it, and I think I need to look closer at Janie in Their Eyes Were Watching God.
Strong Female Movie:
Evie, V for Vendetta
Princess Leia, Star Wars
Ilsa, Casablanca
Arowyn, LOTR
Elizabeth, Pride and Prejudice
Elizabeth, POTC
Karen von Bixen-Finecke, Out of Africa
When I was younger I loved Maria Michel, Amelia Earhart, Laura Ingalls Wilder, and Julie "The Cat" Gaffney on the Mighty Ducks. I'm still that kid looking for women who have walked ahead.
