Also, “Space Zombies!”, the paperback adaptation of the film, just got some great notes from one of the judges at the Writer’s Digest Self-Published Book Awards: "As a science fiction B-movie fan, I was excited to read a novel version of a zombie film. Space Zombie! did not disappoint me. Now I want to see the movie. I found Macaulay’s story hilarious. What isn’t campy and over-the-top about it? Everything lives up to what science fiction B-movie aficionados will easily recognize as the glory of the ludicrous. The premise, characters and parts of speech are all genuine ‘camp’: “He withdrew a weird ray-gun thingy from under his long, black cloak” (24). I adored the way the humans never noticed a zombie clumping around, making obvious noise, until it was too late. It is so entertaining that the zombies want to merge with the superior cat species and not even waste time eating human brains, however delectable they may be. Ju-jube has convincing cat thoughts and the pussy jokes are exactly where they should be. I loved the impending end of civilization symbolized in the clash of the giant toad and the giant starfish. From the cover art of the book showing a “12 cents” price and all the wonderful elements of campy art on both back and front, I truly found this book to be brilliant. It should be sold in every joke and trinket shop on America’s coastlines, preferably with an option to buy the DVD at the same time. The size of the book is perfect…” — Judge, 23rd Annual Writer’s Digest Self-Published Book Awards.
