John McElwee's wonderful blog Greenbriarpictureshows has an entry dated Jan. 9 on Big Jim McLain, specifically the changes wrought to the film for foreign markets, i.e., turning Big Jim into a drug agent rather than a Commie-hunter, and retitling the film "Marijuana." (!) John (who is a distant cousin of filmmaker Ross McElwee) has one of the most amazing collections of memorabilia with which he illustrates his blog posts.
