Query: Guerilla filmmmaking at its finest!

Who'd have thought that Larry Buchanan, that most reviled of low-budget filmmakers, could pen such a warm, involving, ingratiating and fact-filled overview of his own career? Long regarded with disfavor, Mr. Buchanan explains the whys and wherefores of his cinematic output, showing he did the best he (or anyone) could with what monies and talent were available to him. Sci-fi fans may be disappointed by the short shrift he gives his mid-Sixties triumphs -- "The Eye Creatures," "In The Year 2889," etc. -- but it still adds up to a fascinating look back on a career too often dismissed by moviegoers.
