GATTACA by Andrew M. Niccol - The Script Source

69.
The Detectives quickly weed out those suspects not fitting
Jerome's description - WOMEN, OLD MEN and TEENAGERS. They
are shepherded off the street. A line of IN-VALIDS is formed
several hundred yards long. Detectives begin to laboriously
move along the line, taking finger-prick blood samples from
each suspect - instantly confirming their identities with
portable analyzers worn on their hips.
As if having the idea at the same time, TWO SEPARATE MEN
suddenly bolt from the line, knowing that their blood will
incriminate them. Other Detectives, watching for such escape
attempts, easily apprehend them and escort them to a waiting
police van.
INVESTIGATOR that it is safe to exit his car. The
Investigator appears irritated, only half-glancing at the TWO
MEN already in custody, apparently certain that neither one
is his suspect.
DETECTIVE HUGO
(enthusiastic)
Not our fish, but something stuck
in the net.
The Investigator clearly does not share Hugo's enthusiasm.
The Detective offers the Investigator an age enhanced
photograph, computer-generated from the last existing photo
of VINCENT as a 20-year-old.
DETECTIVE HUGO
This is the age enhancement we're
working with.
The Investigator ignores the photo, preferring instead to
trust his own eye as he wanders along the line of suspects.
DETECTIVE HUGO
(referring to the
line-up)
As you requested, we've kept the
parameters wider than usual.
The MEN they scrutinize are hardly mutants - the differences
between an IN-VALID and a DAN are subtle at best. Some
shorter, some wearing glasses, some with receding hairlines
or bald, many with no discernable physical difference at all.
The Investigator is only halfway down the line before he
turns and starts walking back to his car.
The mystified Detective Hugo follows his superior.
