Essa pessoa parece ser Declan Mulholland, o stand-in da cena deletada em que Jabba the Hutt deveria aparecer:
Mulholland would have been replaced with a stop-motion creature during post-production had the scene not ended up on the cutting room floor. - source
O visual do substituto nunca foi canon; Jabba nunca se pareceria com isso. Por que o rosto dele aparece na capa do official Radio Drama se ele estava apenas de pé onde Jabba deveria aparecer ?
O aquecedor também apareceu em Star Wars: o guia essencial para personagens . O esboço do Guia Essencial reafirmou o olhar de Heater como sendo o de Declan Mulholland de seu retrato de Jabba.
Em suma, "Heater" foi um nome de retcon dado a "Jabba" de Declan Mulholland, e isso se tornou parte do Radio Drama. A capa reflete isso.
The character on the right with the crazy hair is Heater. No, that’s his name… Heater. Truth be told, he was Jabba in the original script. They actually shot these Jabba scenes with the actor who depicted in my painting. Several years later, Lucasfilm reinserted the confrontation scene Han Solo has with Jabba the Hutt outside of the Millenium Falcon, but put a CG Jabba the Hut over the actor who portrayed Jabba in the original filming.
By 1981, when the Radio Drama was produced, Lucasfilm had already started developing Jabba the Hutt for Return of the Jedi. As we all know Jabba is a big slimy slug-like Hutt, and does not speak English. To patch this continuity problem, Lucasfilm changed the name of the Jabba character to Heater for the Radio Drama. But then, in the movies he went back to being Jabba the Hutt for the Special Edition… I know it’s confusing, but Heater, for all intents and purposes, is Jabba the Hutt.
