Astronauts come (back?) to a city ruled by robots. Most people are dead. When people get sad the robots detect it and kill. The robots shows a happy or sad smiley corresponding to their analysis of the person being checked.

I think the dead people were used as fertilizer for the food production. The robots got their instructions wrong trying to create happiness.

  • Welcome to the site. When did you watch this film, and when do you think it was made? Also, was it in black & white or in colour? Commented Apr 26, 2021 at 12:27

    That is pretty much the plot of Doctor Who Series 10, "Smile", but it's likely it was used before.

    Whilst the accepted answer is correct, anyone searching on this title may also be looking for a 1980s Doctor Who series, The Happiness Patrol. People who are visibly sad are executed by Kandyman, a psychopathic robot obsessed with confectionery. (Turned an answer into a comment instead, since we have a correct answer.)

    @Graham perfectly fine to leave it as an answer, as you said; other people will come here and may not be looking for the same one as op.

1 Answer 1


Doctor Who Season 10 episode 2 "Smile"

The Doctor brings Bill to a future human colony, where cute EmojiBots work as willing servants and make sure everybody's happy, but if they're not happy, they're harvested.

    That image looks so much like that scene in Psycho Pass which does something similar.
