Discussing the various underground influences in "Yellow Submarine", author Stephen Glynn identifies the segment featuring "It's All Too Much" as being among the film's "most daring sequences". Led by art director Heinz Edelmann, the animation for the song reflects the influence of psychedelic artists such as Hapshash and the Coloured Coat, who in turn were inspired by the work of the nineteenth-century illustrator Aubrey Beardsley. Referring to London's UFO Club, for which the Hapshash team designed promotional posters, Glynn considers the scene to be a cinematic version of Unlimited Freak Out – "a 'happening' that sought to create a totalising mind-expanding environment involving music, light and people".
