Zombie movies, as well as movies influenced by zombies, that I’ve seen.
I highly recommend the British TV series Dead Set.
10/15/2011: The 1936 film The Revolt of the Zombies is poorly made, but it’s interesting to study the characters’ agency in the face of the film’s mix of exoticism tropes.
9/26/2012: The Cuban film Juan of the Dead (Juan de los muertos) (2011) isn’t great, but along with the offensiveness and lack of budget is plucky, laconic heart. Also, zombies as “dissidents.”
9/3/2013: I’d add the TV shows In the Flesh and the Canal+ adaptation of Les Revenants (The Returned).
Also, I wanted to add that, while zombies are a horror trope, zombie films can fall outside the genre and become more accurately classified as sci-fi action thriller, drama, or comedy.
