Gattaca

Vincent Anton Freeman is the protagonist of Gattaca. He, unlike most of his generation, was conceived without genetic selection, and is therefore at risk for many disorders and has a shortened life expectancy. Vincent dreams of becoming an astronaut, but knows his genetic inferiority makes this dream almost unattainable. He therefore does the only thing he can think of that will help him attain this dream: posing as a different individual with a better genotype. Vincent buys DNA from someone who is genetically superior and passes himself off as a "valid." He is ultimately granted his chance to live his dream when the doctor in charge of genetic screenings fakes his genetic validity because he wants to see if Vincent is able to go beyond his physical limitations.

Jerome Eugene Morrow is the individual whom Vincent is posing as using samples of hair, blood, urine, etc. Once an accomplished swimmer, Jerome became depressed after placing second in a competition, and attempted suicide by jumping in front of a car, leading to his paralysis. The incident occurred abroad and is unrecorded; therefore, Jerome’s nearly-flawless genotype is ideal for deceiving Gattaca.
