Gattaca is a 1997 American science fiction drama film. The film presents a biopunk vision of a society driven by liberal eugenics. Children of the middle and upper classes are selected through preimplantation genetic diagnosis to ensure they possess the best hereditary traits of their parents. A genetic registry database uses biometrics to instantly identify and classify those so created as valids while those conceived by traditional means are derisively known as in-valids. While genetic discrimination is forbidden by law, in practice it is easy to profile one's genotype resulting in the Valids qualifying for professional employment while the In-Valids who are susceptible to disease are relegated to menial jobs. The movie draws on concerns over reproductive technologies which facilitate eugenics, and the possible consequences of such technological developments for society. It also explores the idea of destiny and the ways in which it can and does govern lives. Characters in Gattaca continually battle both with society and with themselves to find their place in the world and who they are destined to be according to their genes.
The title is based on the initial letters of the four DNA nitrogenous bases (adenine, cytosine, guanine, and thymine). During the credits the letters G, C, T, and A are all highlighted.
