Margin Call?
But I was more looking at the tech ones eg. hardware/software I know HFT, I don't mean that
I'd throw The Aviator in there but again not tech, but that idea swimming in money, possibility, changing the future. One day a movie about EM ha.
Anyway I wish I had my thing I was chasing/something novel. Maybe one day.
The Circle is another that doesn't belong here but has that "cool tech company" vibe.
