>>>Then you're into a period piece, which would cost loads more to make
Good point, Foxtrot25.? However,
1] You're into a period piece anyway setting the story beginning in 1975 -- more than 40 years.? Which means it's going to cost more.? Granted not cost as much as setting it in WW2, but...
2] How are you going to persuade the audience that the women deserve recognition if you don't show what they did to deserve it?? Like the movie "Hidden Figures".? It didn't focus on the struggle of Black women to gain recognition for their contribution to the US space program decades later.? The movie shows them in that time period struggling to achieve and win respect and recognition.
Show, not tell.? That's the best way to tell a film story,? persuade a movie audience.
