Reminds me of Traveling Salesman (2012) [1], also set in P = NP and discussing the ethics of selling the algorithm to the government. (Literally discussing, it's a low-budget 4-men-in-a-room movie).

I can't say the whole film is worth the time, but I really loved how in the first minutes it establishes it's alternative history by a single sentence: introducing a scientists who "in 2008 was awarded ... the fields medal for his proof of the nonexistence of one-way functions"
