In a new extended clip from Shane Acker's animated post-apocalyptic tale 9, a philosophical disagreement over how to confront the many dangers of this world quickly turns urgent, as the movie's rag doll heroes try to fend off an attack from above. Pursuing them this time is a pterodactyl-like machine made of knives and sharp points. The clip offers up some fast-paced action, but along the way we also get cool panoramic views of the post-human landscape still littered with the broken architecture and detritus of its former occupants.
