Open Grave is a 2013 zombie suspense film directed by Gonzalo López-Gallego.
A man wakes up in the wilderness, in a pit full of dead bodies, with no memory and must determine if the murderer is one of the strangers who rescued him, or if he himself is the killer.
This film has examples of:
- Bittersweet Ending: Even though Jonah and Brown Eyes survive the military sweep, everyone else in the group is dead and Jonah loses the instructions given to him by Sharon who dies from the knife wound and never wakes up.
- Easy Amnesia: Nathan remembers everything by finding his glasses. Other characters figure things out somewhat more gradually, but still invoked.
- Never Trust a Trailer: The trailer leaves an impression as if the group try to defend themselves against the 'infected' and military rather than fighting amongst themselves trying to figure out what's going on.
- Our Zombies Are Different: Plague/technically living type. The 'infected' remain somewhat more self-aware and intelligent than the traditional zombies. They are also somewhat less agressive, although this trait is somewhat inconsistent throughout the film. In addition as the people never die before 'turning', the process is more gradual resulting in odd behaviour and agressiveness even during the lesser stages of infection.
- Poor Communication Kills: Probable reason for why the soldiers were ordered to kill everyone. Had Nathan told them that they had a cure, someone might have had second thoughts about wiping out the researchers they were supposed to meet up with for the cure a few days earlier.
- Scary Scarecrows: The group has been using human bodies as scarecrows to keep the infected away from the house.
- Selective Obliviousness: Lukas after watching the tape and still blaming Jonah for everything.
- Trailers Always Spoil: Trailer shows the group hiding from the military, thus giving hints to as what is coming on the 18th and also that they are not there on a rescue operation. The trailer also shows the "infected" which are not revealed for a while in the actual movie.
- Zombie Infectee: Lukas ignores his headaches and other's comments on his odd behaviour. Justified in that neither he or the others remember how the infection worked, at least until Lukas himself finds the video camera explaining most of the things and still ignores his headaches.
