 The producers wanted the musical to appear like a " corny and low @-@ rent production " . The ensemble includes 10 actors from ages eight to twelve . Though professionals , the child actors perform with a " realistic lack of polish " , as they are playing non @-@ professional children of Scientologists , performing in a holiday pageant . The chorus portrays Thetans , and the reactive and analytical portions of the mind are depicted by two children who share a conjoined right brain costume . During the Xenu story , the narrator is outfitted in a cardboard robot suit , and the actor portraying Xenu wears a " tacky headdress " . Staging , costumes and set design are all made to appear to be the " earnest work of schoolteachers and supportive parents trying to provide a colorful and cheery atmosphere on a small budget . " The stage design includes a " colorful , crayon @-@ colored backdrop of space age @-@ like , semi @-@ circular set pieces . " Costumes include white robes , rainbow @-@ striped socks and tinsel halos . Props used to denote locations include " a waving cardboard palm frond for Hawaii , a street sign and cell phones for New York . " The musical ends with a tableau vivant , where the audience sees the cast standing at the back of the theater holding candles and singing cheerfully as a door closes and they are blocked from view .
