I watched "American Made" (2017)
https://en.wikipedia.org/wiki/American_Made_(film) - a Tom Cruise film in which he plays Barry Seal, a soon to be ex-TWA pilot who flew for the CIA and the Medellin Cartel in the late 70's to 80's. He made a ton of money, didn't seem to know how to open an off shore bank account, lost most of it, turned informer for the government and of course got executed for it. The CIA seemingly just wrote him off and didn't try to protect him much at all. Cruise does play a slimy guy quite convincingly.
I'd give it 3.5 out of 5.
