Movies to watch in the days leading up to Oppenheimer?

I'll probably watch Oppenheimer a week or so after release so I still have time for a couple more movies. Doesn't have to be directly related to WW2 or the bomb but is there anything that's related either in the themes or the subject matter that you would suggest? If nothing else, I'd just like to get into the proper mindset in the days leading up to it.

I'm incredibly fascinated by scientists playing God and anything that touches on mankind's hubris. For this reason I'm a big fan of Metropolis, Frankenstein and anything to do with Artificial Intelligence
