First law of nerdy film: If you invoke the name of the Gygax in your retro throwback practical effects fest, you A) better deliver and B) will automatically win credibility points with the kind of weirdos and wackos who want to spend Friday night guzzling pizza and beer while watching a retro throwback practical effects fest. Or, if you re Mimi (Hanna) and Luke (Myre) it would probably be pizza and something equal parts CO2, Aspartame, and food coloring while sneaking downstairs to watch a late-night cable access horror show while beaming throw pillows at each other s heads, zipper side first.
