Circle (not to be confused by The Circle). A sci-if/ psychological thriller on the theme of moral philosophy. This is a B-movie so don't expect too much of it, but I will say this: it is one of the best B-movie films I've seen in years. Intriguing, entertaining and thought-provoking: perfect late evening fodder.
A group of 50 strangers wake up, after been kidnapped by an unseen, presumed alien force, in a room standing in a circle. If anyone tries to leave the spot they're standing on they are killed by some kind of electric bolt emanating from a central console. And ever two minutes, the electric bolt will kill one of them. Soon they work out they might be able to influence who the bolt kills next, and that's when all the moral dilemmas and prejudices arise as the remaining individuals argue about who deserves to live more than others.
Overall a highly satisfying film, more so as we had put it on with very low expectations.
