Coalminer’s daughter breaks baker’s heart
Star Wars? 
That one epsiode of GoT? That’s the only baker I can think of.
Sorry, no and no. I’ve never seen GoT, and I’m not sure who the coalminer is in Star Wars, so I can’t say whether they are reasonable guesses.
I was being an idiot
There is a movie called The Coalminers Daughter?
So there is. Not the answer, I’m afraid. I’m sticking to titles I think most people will have seen.
I was being an idiot also, so @Captbnut wouldnt feel lonely 
Ps i have no idea. I’ll be quiet now.
Obviously The Day of the Triffids. (Yes, I know it’s been answered.)
Fantastic Beasts?
Not Fantastic Beasts
Sherlock Holmes? Although I don’t quite see how Irene Adler would be a coalminer’s daughter, nothing I could turn up on the internet about her says anything about where she’s from except “New Jersey” don’t tell me only coalminers live in New Jersey.
The coalminer film I can’t get past is Billy Elliott
Not Sherlock Holmes. The woman in the film is definitely from a coalmining district.
Not Billy Elliott either. Surprisingly, it’s not even set in the North of England.
The Hunger Games
Thanks for that @COMaestro. You’re up.
omg that has to be it. arg I have seen the movies and read the books… I actually saw the first movie in Portland. We were visiting at the time
