The Vespa seen in the closing credit sequence belongs to director Kazuya Tsurumaki. Apparently, he can't get it to work.
Though credited with a question mark, the voice of Miyu Miyu is provided by Evangelion director Hideaki Anno.
The woman interviewing director Kazuya Tsurumaki on the commentary track is Maki Terashima-Fukuta, one of the executive producers of the U.S. version of FLCL.
Amarao's eyebrows are actually sheets of "nori", dried seaweed that is used in sushi. The nori was digitally scanned into a computer.
In episode 2, Haruko fixes her Vespa after crashing it into the Medical Mechanica factory. Among the parts she installs is a Mobile Suit Gundam RX-79 robot model.
In the second episode, Naota tells Haruko that the reason his dad acts so strange is because "He wrote an 'EVA' book a while ago". (in the English version, "He wrote a book on the deep mysteries of 'EVA.'"). The show he's talking about is _"Shin seiki evangelion" (1995)_, a hit series made by the same animation studio with some of the same staff, and that line is a tounge-in-cheek reference to the confusion the final two episodes caused when they first aired. The director and writer of this show, Hideaki Anno, is also the uncredited voice of Naota's cat Miyu-Miyu.
Director Cameo: ['Kazuya Tsuramaki' ] the director says, "Tabun,"(which means "probably") during the preview for the 6th episode which plays at the very end of the 5th episode.
The moped driven by Amarao is not a Vespa but a Japanese moped called a Rabbit. According to the director it is much rarer then a Vespa.
Every guitar that appears in the series (with the exception of the mini flying v sling shot) is a real guitar.
Every three episodes, Miya-Jun's car is destroyed.
When Miya-Jun's car is trashed by Canti (episode 3), a miniature Kenny from "South Park" (1997) can be seen among the flying wreckage.
Haruko refers to Naota as "Taro-kun" several times during Episode 1. Taro is perhaps the most generic name in Japan for a boy, and it used as a placeholder for unidentified Japanese males (like John Doe).
GAINAX Studios, a cartoon production studio in Japan, made this as "a break" from normal anime, which fans of the series use as an excuse for the insanity that occurs. In reality, the show, despite having a plot, is really just crazy.
Director Kazuya Tsurumaki personally oversaw the English dub in America. He was very insistent that the voice actors/actresses from the English dub had the same "essence" as the Japanese actors/actresses. He said he was very pleased with the characters for the English dub, and was especially pleased with voice actress Kari Wahlgren's Haruko.
Mamimi is only once shown in the process of setting fire to anything, even though she smokes almost constantly. This is in Episode Two (FireStarter) In the rest of the series, when she starts a fire, she turns away from the camera in such a way that the flame cannot be seen.
Haruko's bass guitar is a left-handed AzureGlo Rickenbacker 4001. Atomsk's is a 1961 Gibson EB-0. Naota's appears to be a 1967 Gibson Flying V
Atomsk is named after a novel by Cordwainer Smith.
Despite the title's spelling, the title is intended to be pronounced "Furikuri" ("Fooly Cooly" in English), not "eff-ell-cee-ell." The letters "FLCL" are a romanization of the four Japanese Katakana characters that spell the title. "Furikuri" is an oft-repeated term by the characters but its meaning is never specifically explained.
The teacher's car that is destroyed by Naota is a VW beetle
The voice actor for Naota is the same one that played Rita Repulsa from Power Rangers.
The creation itself of FLCL is an amazing work of art that draws techniques from classic American literature and modernist ideas. To fully understand the depth, the audience must be familiar with literary techniques and purposes. The characters, social interactions, and plot elements are all metaphors overlapping each other to cross-hatch the bigger picture that is, coming of age. The finer pieces are up for interpretation. FLCL creates analogies on a variety of social fronts. The series uses sexually ambiguous imagery similar to create humorous themes as _"The Ren & Stimpy Show" (1991)_ did in America during the early 90's.
