Movies set in early 1900s/Depression?

I have to do a movie trailer for "A Tree Grows in Brooklyn" for English. We're allowed to use clips from real movies, but NOT clips from actual adaptations of the book (so I can't use clips from the old movie of ATGIB). So, I'm looking for movies that feature poor families in the early 1900s or the Great Depression. Specifically, I'd like films that have young female protagonists (like the novel).

So far I have:

-Cinderella Man

--Meet me in St. Louis: scene where Esther dances with her boyfriend

-Angela’s ashes

-Secret Garden

-Narnia

To kill a mockingbird

a little princess : scenes where she walks in the street

Any other ideas?? 10 points :)
