When a man (Sharlto Copley) wakes up in a mass grave, with no memory of what happened to him, he must determine if the murderer is one of the five strangers who rescued him, or if he himself is the killer.

Open Grave is a tense, well-acted film, and it really works when you know as little about the story as possible. It’s creepy and unsettling and it will definitely make you jump a few times.

The atmosphere that’s set up from the very beginning is foreboding and unsettling. The deep pit the protagonist wakes up in is in the middle of nowhere, with the only house nearby being occupied by five people who either can’t remember what happened either, or can’t communicate what they know.

The way the story is played out means you are trying to figure out what’s happening at the same time as the characters are. The suspense is maintained throughout as different characters discover different elements to the truth but as they have no reference point, it still doesn’t always make sense to them – or they jump to what could be a very wrong or dangerous conclusion.

Sharlto Copley is brilliant as a man who is not sure who to trust and, as he gets flashes of memory, he’s not even sure he can trust himself. The rest of the cast are great too, managing to juggle the right amount of fear and suspicion with the desire to survive.

Open Grave is a compelling film that’s sharply directed and knows how to build the tension. The way it sprinkles in answers throughout is great as it’s not until the end of the film do you see how everything fits together. 4/5.
