Trinity used an actual exploit (ssh IIRC). This sets it apart some movies like Jurassic Park with the girl looking at some UI made of 3D shapes and says "unix, I know it).
Or NCIS - of which I copied for an awareness training the part where the two geeks "go though the firewall" both on the same keyboard.
Also, the Jurassic Park scene to which you're referring was a real picture of SGI IRIX's 3D file manager. It was visual fluff, but functional visual fluff.
Jurassic Park: That was the Button Fly Demo UI from SGI IRIX. So at least it wasn't a complete mockup. (But nor is it the same as "knowing unix". If she knew unix, she would've been complaining more.)
