I love that movie too. It’s amazing how well it holds up for it being, in many ways, a tech-focused movie - I mean, yeah, the tech is very much dated and completely a product of its time, but it doesn’t look at all ridiculous. Undoubtedly probably helps that it was pre-WWW/popular internet.

I think it helps that the technical concept that drove the main plot was a very real and still-present risk to public key encryption systems.

Whenever the line „they don’t make them like this anymore“ comes up wrt movies, I think of „Sneakers“ and „The Hunt for Red October“.
