The area of California in which this was filmed bears very little resemblance to the area of Korea in which the story allegedly takes place. Likewise, "Han" definitely looks more Hispanic than Korean. (NOT FOR PUBLICATION: I was stationed about six miles South of the DMZ for 14 months. I know whereof I "speak" on both counts. It's hard for be to believe that there was no Asian boy in California who could have played the part.)
Robert Goshen's (Lt. Nero) voice is dubbed.
