Urban legend has defined this title as a filmed version of Karel Capek's play R.U.R., apparently on the strength of stills which show the film's robots bearing the logo, RUR. In fact, no screen credit is given Capek or his play, and the plot resembles the play only in the general sense that both concern robots replacing human workers. This film, however, portrays this as a disastrous and villainous idea, in stark contrast to Capek's Utopian view of robotics. In addition, its robots are emotionless and mindless machines, rather than the emotional and rational androids of the Czech play.
