Off the top of my head, here are a few that a 10-year old girl might like.
She might like Goonies, Explorers, or ET, though they’re kind of boy-centric (not in an inappropriate juvenile way, though).
There was a not-very-good version of Nancy Drew recently.
*Sabrina * - Humphrey Bogart/Audrey Hepburn version
*Roman Holiday *- Audrey Hepburn/Gregory Peck
Pride and Prejudice - Jennifer Ehle/Colin Firth Version
Strictly Ballroom - Australian ballroom dance. What’s not to love?
The Secret of Roan Innish - Just because
StG
Ever After (Glad to see I’m not the only one to nominate this)
A League of their Own
Legally Blonde
Labyrinth
The Neverending Story
She’s seen quite a few of them, but I forgot a lot of these suggestions too. Thanks guys, I knew you’d have some great ideas!
If she’s willing to watch old black and white movies, how about Bringing up Baby? It’s a completely silly movie that I think a ten year old girl would like.
