Production for "The Beast" began in September 1994, simultaneously with "
Angel Attack", and ended in May 1995.
Yōji Enokido and
Hideaki Anno wrote the script, while
Kazuya Tsurumaki served as director for the episode. Unlike the previous installment, Gainax produced "The Beast" with a non-linear narrative, interspersed with continuous flashbacks and scene changes; Anno remained dissatisfied with "Angel Attack" during the post recording and described it as "a failure", since it couldn't beat the first episode of the original
Mobile Suit Gundam series. He was disappointed by the script and the structure, judging it "three minutes too long", so he completely reworked "The Beast" in the middle. Continuing their work from "Angel Attack", Anno and assistant director Masayuki composed the
storyboards. For the combat between Eva-01 and Sachiel,
Takeshi Honda, chief animator for the episode, and
Yoh Yoshinari handled the key animation. The Japanese title "Unfamiliar Ceilings" was decided on in 1993, when Gainax wrote a presentation document of
Neon Genesis Evangelion titled . The beginning of a battle between an Angel named Raziel and berserk Unit 01 was planned for "Angel Attack" in the
Proposal, but during production it was moved to "The Beast" and the Angel changed to Sachiel. For the battle between Eva-01 and Sachiel Gainax created integration between the backdrops and the moving objects on several levels. The fight was initially close to a
tokusatsu battle in the style of
Ultraman, but, according to
Yūichirō Oguro, during production Honda apparently decided to give the scene a more anime style. Yoshinari took care of the battle scene, trying to draw the shoulders and face of the Eva-01 using rulers. The staff also made extensive use of close-ups during the episode. During the battle, before Eva-01 berserk mode, the crew zoomed in on Shinji's face in close-up giving the idea of wide-angle lens, and deforming it with
CG. For the image of the Eva-01 destroying the AT Field, Hideaki Anno took inspiration from the image of tearing clothes, considering them as the most elementary form of protection for human beings; the concept was included in "The Beast" with no philosophical implications, and Anno thought about its meaning as the "walls of the heart" during the production of the latter part of the series. He also added the term Human Instrumentality Project, one of the most important concepts for the plot, by improvising and without having clear ideas about it. "I still had no idea about what it was going to 'complement'. ... It's just a verbal bluff", he said. In the hospital scene, where Shinji stands alone in an empty corridor, contrasts of light and shadow were used, keeping the scene monochromatic, to represent Shinji's inner emptiness. Furthermore, the main staff used real brands in "The Beast" scenes to depict a realistic fictional world, including a
Mitsubishi Fuso truck, a
Sony Digital Audio Tape and
Yebisu beer.
Yuko Miyamura,
Katsumi Suzuki,
Megumi Hayashibara and
Takashi Nagasako voiced unidentified characters in "The Beast", while Nagasako, Suzumi,
Motomu Kiyokawa and
Koyasu Takehito voiced the men of the Istrumentality Committee. Besides the original soundtrack, composed by
Shiro Sagisu, Gainax also used
You are the only one by
Kotono Mitsuishi, Misato's voice actress, published in her image album
Lilia ~from Ys~ (1992). British singer Claire Littley sang a cover of "
Fly Me to the Moon" named "Normal Version" which was later used as the episode's closing theme song, replaced in late home video editions by a "String Version" sung by the same singer. ==Cultural references==
