Zombiemania

This 2008 documentary directed by Donna Davies (available for Instant viewing on Netflix) is slickly produced, blackly humorous, and thoroughly entertaining.  It features interviews with special fx maestros Tom Savini and Greg Nicotero, authors Max Brooks, Wade Davis, and Brian Keene, and (best of all) legendary film director George Romero.  With the help of such commentators, Davies traces the history of the zombie in horror cinema (a slew of grue-some film clips are included) and ponders the monster's cultural significance.  Modern phenomena are also addressed, such as the rise of zombie walks, Brooks's Zombie Self-Defense Lecture tour, and even the work of a zombie portrait artist.  As fun as it is informative (e.g. Romero offers some wonderful anecdotes about the filming of Night of the Living Dead), Zombiemania is a must-see for every Undead-head wandering around the Macabre Republic.
