When it comes to movies from that era, I sorta followed my mother's tastes. So I know the version of Little Women with Elizabeth Taylor playing Amy backwards and forward, in French and in English. Ditto The Sound of Music.
Here, we have the Sissi movies on TV pretty much every holiday... Though you have to be French or German to know what those are, I believe.
Sp it's not that I don't know any Old Hollywood movies. They're just very specific to whatever was popular here when my mother was growing up. And my mother grew up poor, so there isn't a wide variety.
Gone With the Wind is my aunt's favourite. My grandmother's was Doctor Zhivago. I also know those two movies pretty darn well as a result. Not a fan.
I will definitely check out Wizard of Oz because I'm sure I'll come across it at some point.
