Seeing the movie, I was surprised that a PAR even existed or was
possible. I don't see how ATC could have a better idea of the
aircraft's exact position than the pilot, given that the pilot has
many more instruments.


PAR is a VERY accurate radar for approaches. There aren't many
around these days outside of military fields. It's a special
scope different from the normal radar that looks up the final
approach path. It uses the radar returns for both horizontal
and vertical guideance, it does not need a transponder.
