Before filming their post-apocalyptic film opening, the filmmakers had to consider many elements like set, sound, lighting, costumes, makeup, props, and setting. Makeup was minimal to make the character look rough, and fake blood was used. Careful consideration was given to sound design, including diegetic sounds, music, and a news broadcast voiceover. Low key lighting was used to set a dull mood. Costumes were scruffy and worn to fit the genre. Authentic props like a rifle, incinerator, and medical supplies were gathered to make the set realistic.
