9 Movie Heroes & Villains That Didn't Know Each Other Existed

9. Alan Grant & Dennis Nedry - Jurassic Park

Jurassic Park's big hero is of course grumpy paleontologist Dr. Alan Grant (Sam Neill), while the man responsible for the park's catastrophe is disgruntled computer programmer Dennis Nedry (Wayne Knight), who causes the dinosaurs to escape while trying to smuggle frozen dinosaur embryos off the island.

And yet in spite of this, these two forces operate entirely independently of one another, and never end up crossing paths throughout the film, nor even knowing of each other's existence.

Nedry is "only" trying to commit corporate espionage, and endangering Grant and company is really just the collateral damage of that, while Grant is in the thick of it for the entire movie and so doesn't have much time to ponder why the dinosaurs escaped their containment.

Though it's reasonable to assume that Grant certainly found out who Nedry was during the subsequent investigation into the disaster, he's absolutely none the wiser while it's happening.
