Unlike previous resource videos, A is for Asthma was reshot in Spanish rather than simply being dubbed. The rest of the main cast of the video (Gabriel Velez, Carmen Osbahr and Emilio Delgado) were Spanish-speakers, meaning Kevin Clash as Elmo would have to be dubbed. Belizario was hired to be the Spanish voice for Elmo and subsequently recorded his lines as a reference for Clash to learn. Clash (who was in China at the time) instead memorized the cadence and rhythm of Belizario's vocals. When it came time to film the video, Belizario was on-set, sitting underneath the camera and reciting his lines live, as Clash lip-synced Elmo to his vocals.
