The close-up of the alarm clock Michonne (Danai Gurira) awakes to in scene 5 is similar to the alarm-clock in the comedy Groundhog Day (1993), starring Bill Murray. In the movie, Murray's character repeats the same day over and over; each day starts over with a close-up of the alarm clock going off at 6:00 am. The clock in this scene is the same model, set to 6:30.
