Choi and Dujour
Choi (played by Marc Gray) is assumedly a bluepill who appears in the first movie buying illegal software from Neo, for which Choi pays $US 2,000 in cash. Choi, his latex-clad girlfriend Dujour (played by Ada Nicodemou), and several unnamed and unspeaking friends arrive at Neo's door after he had been mysteriously told to "follow the white rabbit". When Neo notices that Dujour has a tattoo of a white rabbit on the back of her left shoulder, he accepts their offer to go with them to a goth club, where he is approached by Trinity. Going to the club and subsequently waking up late for work the following day set the stage for the rest of the film, though Choi, Dujour, and their friends are never seen or alluded to again.
Much of Choi's dialogue foreshadows the rest of the film: "I know. This never happened. You don't exist", "You need to unplug", and "Hallelujah. You're my savior, man. My own personal Jesus Christ" (A tribute to Depeche Mode).
These names would appear to be inspired by French language; "Choi" and "Dujour" resembles the French phrase "Choix du jour," meaning "Choice of the day".
Choi, originally described as a Chinese man in the shooting draft of The Matrix screenplay, could also possibly refer to the choi matrix from Man-Duen Choi's theorem on completely positive maps in mathematics.
These two characters appeared in an early draft script for The Matrix Reloaded, where Choi played a ship's captain and Dujour played a crew member, insinuating that the pair were not completely unaware of the part they were playing in freeing Neo from the matrix in the first film.
