The line comes from The Matrix, the 1999 film in which Hugo Weaving plays Agent Smith, a program hunting the hacker Neo. Smith refuses to use Neo's chosen name and instead calls him Mr. Anderson, using his ordinary civilian identity, Thomas A. Anderson, as a way to belittle him and assert control. The formality became one of the film's most quoted habits, and clips of the address spread through fan edits, parodies and soundboards. It remains popular because the phrase alone instantly evokes the film's cold, corporate villain and the tension of being watched.
