Jonah (Sharlto Copley) wakes up in a mass grave next to countless corpses. A mute Asian girl (Josie Ho) helps him out of there. He suffers from amnesia and cannot remember what happened and how he got there. In a house nearby, he meets several others, including Lukas (Thomas Kretschmann), Nathan (Joseph Morgan)and Sharon (Erin Richards), however all of them have lost their memory, too! Step by step, they explore the surrounding area, recover their memory piece by piece and find out that they are in a terrible danger...The whole movie is in a similar situation like the "Lost" TV series, because people who don't trust each other have to explore unknown territory. There is just some more horror thrown in for good measure. All in all, "Open Grave" is a really good movie. The story remains full of suspense, because the main characters don't know who they are: the good guys or were they involved in that mass murder?

I was thoroughly grateful for this new twist for its genre!! To not add it to the generalized "time & time again" type of film genre that's been made yet again.It's of course common of all the genre's(&their accompanied sub-genre's)of films being,&have been made,although in my opinion it's especially more commonly seen when it comes to the Horror-Mystery Thriller movies(even if you include Sci-Fi into the mix w/havin the same mentioned sub-genre's),&even when it comes to also the movies generalized,like this one,as a"B- Minus"film.I was intrigued when I'd read the movies summary,&hadn't ever heard of it either until I happened to stumble upon it here(like I do w/Many other movies as well),so I gave it a chance,&am really glad I did!!Not only am I Grateful the director,producer,writer,&so forth,had come up with a different overall direction on the movies concept,&in a good way!Plus the actors may be ones I've at least never heard of before,but they All did their parts awesome,to where that all involved had pulled together an excellent movie to watch!!I admit that I was expecting to possibly chalk it up as either: yet another "B-Minus Movie" where *Yawn*I'm bored,or 5 minutes into a film & you can already tell its a Big Flop,or even is somewhat decent yet is maybe even predictable...We have all been there,& have seen these types of movies to where even you find yourself watching a flick thinking over & over "Maybe it'll get better soon...maybe it'll get better soon...",but didn't because next thing ya know it over,or it's just that bad you don't even bother to finish the movie.I've definitely had my fill of badly executed(literally)films where if in the right hands &maybe budget also was higher,it'd have a better overall rating w/reviews too,because the summary and story line of the film is a good one,buts sadly made.All that being said,I hope my reviews of some help without giving away any spoilers,&that others give it a try!!!

One very tricky movie, that does change pace and has a lot of twists. The formula of people forgetting their pasts, but having to stick together is not new. But it is made very entertaining in this movie right here. It could have been a bit better or richer in the story department or the telling of the story.I did miss a punch or two, that would've made this really good. As it is, the actors really carry their weight, with an ending that is kind of sad, because it seems an easy way out. Something you kind of expect this movie to do. Although there could've been an easier solution. But that option is not taken. Decent thriller, that will keep you entertained.

6.3 out of 10 for this movie? Are you kidding me? I have seen my share of horror flicks and Open Grave is certainly ranks among the best, at least in my opinion. It's a slow burn and that perhaps could be the reason why it received such a low rating. Yes, it does not have the frenetic energy of World War Z or the glossy sheen rendered by CGI overload in The Cabin in the Woods or the gross out factor of Hostel. Open Grave stands on it's own by the virtue of it's ability to deliver a suspenseful story which starts as a murder mystery and then evolves into a completely different beast while at the same time pitting the stripped personality of central characters against their primal instincts- all set against a very bleak and rather increasingly strange background and no one has a clue as to what will happen next. The characters, just like the audience, make one gruesome discovery after the other, not just about their circumstances but about themselves as well since they are all amnesiac but one. Who is that one person and why is that one person so important? The suspense is edge of the seat and it leaves you guessing right up to the very last frame of the film. How many horror movies in your experience can claim that distinction? The story that Open Grave tells is certainly macabre or at least the treatment is, which I must say is handled rather very well.If you are not too nit-picky about revealing accents, as some reviewers are, and like a good story with some very good acting, writing, cinematography, and a slow and steady buildup with a decent payoff then this movie is for you. And, don't worry- there will never be a mind numbing sequel/prequel to this one; unlike Saw (one of my favorites) this one forces the audience to use their brains rather than pulling a fast one.
