Purely curious - How do you conclude that a given font is the one used, and not just a similar-looking one? Is it simply a process of eyeballing all the letters available? I'm especially curious for stuff like your identifications on The Negotiator, where you said they were existing fonts that had been condensed.
It is just eyeballing it, but there's a lot of quirks that make it clear it's this particular font and not just a similar-looking one. Like, there are many copycats of FF Blur, but FF Blur has (among other things) a weirdly short and thin M, which you can see in "TIME" and "SAMUEL".
Here's some of FF Blur's competitors. They're similar, but you can still tell them apart.
There have been a few cases where I got a font wrong because I didn't look closely enough. When I know there are multiple similar fonts, I make sure to verify which one it is, but sometimes when I thought a font was unique it actually turns out to have copycats.
