Gattaca

Ethan Hawke is Vincent - a naturally conceived yet sickly child, compared to his brother Anton - a son who has been artificially conceived and the chosen foetus among several in the quest to eliminate genetically inferior traits. However, as Vincent grows, his one ambition is to fly on a space mission, and this becomes his all-consuming aim. He begins work at the space agency 'Gattaca' as a grade G cleaner. Yet he is driven to the extent that he is sold the genetic identity of Jerome, a healthy high-flyer who has been crippled, played by Jude Law. Vincent has to undertake painful surgeries and trick the constant genetic ID tests in order to fully assume Jerome's identity - and to fulfil his ambition for space flight. His new identity is soon in jeopardy when a murder is committed, and the premises of Gattaca are scoured for DNA evidence of anyone listed as 'in-valid'.
