If you're interested, Terminator 2 - Judgement Day is just about the best action/sci-fi movie with emotional depth that is out there.
Boen's minor antagonist role is that of a psychiatrist stunted by decades of seeing the worst, and he skillfully walks on a tightrope between scientific interest turned sadistic impulse and halfway well meaning treatment of his patient. One minute you just want to punch his face, the very next you'd like to tell the protagonist to not treat him that brutally. A small role, but a perfect performance in a perfect movie.
