Even if you’re not particularly claustrophobic, naturally none of us likes to feel trapped. So of course, a common theme or setting for thrillers and horror films is exactly that. The protagonist is trapped, usually by a murderous psychopath or even perhaps a supernatural being, and we watch with our blood pressure rising, hoping they somehow manage to get out alive.
10 Cloverfield Lane, directed by Dan Trachtenberg, starts with this relatively simple and common concept. Girl is trapped in a room, possibly a basement. Girl is chained to the radiator. Girl, of course, has no idea how she got there. Or how she’s going to get out.
