A single line on George’s own Japanese professional profile is all that survives of Collector (コレクター), listed as 1986 work. That listing carried a “CM” prefix, the standard Japanese shorthand for a television commercial — but Nintendo’s own 1998 filmography of George, reproduced in full on this site, lists a “Collector” entry for the same year among his films, not his commercials, sitting directly next to Big Trouble in Little China. The two lists disagree and nothing here resolves it.
No matching commercial, film credit, press coverage, or behind-the-scenes material has surfaced in either English or Japanese.
This is a credit and nothing more: a title in a list, from the year George’s Los Angeles shop was newly active. Until a copy or a contemporary listing turns up, that’s the whole page.
