This survey of the zombie-entertainment phenomenon from director Alexandre O. Philippe (The People vs. George Lucas) feels designed for an afternoon session at a comic convention: There's some good info along with a lot of strained comic bits, fan footage and merchandizing ops.
Academics report that the modern shuffling and flesh-eating zombie, though rooted in African and Haitian folklore, may be about how mass culture eats our brains. The watershed zombie moment was George Romero's 1968 no-budget shocker, Night of the Living Dead, although Romero says he didn't identify his creatures as zombies until a critic pointed it out.
Interviews with Romero, Simon Pegg (Shaun of the Dead), Max Brooks (World War Z) and comic-book writer Robert Kirkman (The Walking Dead) explore the genre's evolution and the raging debate over whether slow or fast zombies are more horrifying.
