Bicentennial Man is a 1999 American science fiction drama film starring Robin Williams and Sam Neill. Based on the novel The Positronic Man, co-written by Isaac Asimov and Robert Silverberg, which is itself based on Asimov's original novella titled The Bicentennial Man, the plot explores issues of humanity, slavery, prejudice, maturity, intellectual freedom, conformity, sex, love, and mortality. It was directed by Chris Columbus. The title comes from the main character existing to the age of two hundred years, and Asimov's book was published in the year that the U.S. had its bicentennial.
