Films by directed by women featuring teenager girls. A few of these have adults playing teens early in the film, but mostly this should be actual teenage actresses or documentaries about teenage girls. I’m defining teenage as 13-19, so if a movie features someone who is 11 or 12, I think that’s still childhood. Debate amongst yourselves there. Also I am not including animated films because the few animated films directed by women featuring teenagers are voiced by adult actresses.
Leave suggestions in the comments and I’ll add films to the list!
