The term 'RED PILL CHOOSER IN 'THE MATRIX'' refers to the character Neo, played by Keanu Reeves in the 1999 science fiction film The Matrix. Neo is a computer programmer who is offered a choice between taking a red pill or a blue pill. Taking the red pill will reveal the truth about the Matrix, a simulated reality created by intelligent machines to enslave humanity. Neo chooses the red pill, and is thus known as the Red Pill Chooser in The Matrix.
