There's an American movie, I believe it's probably 5-12 years old, that is suspense with horror elements. The thing I remember most about it is the end, when it is revealed that there are huge bizarre looking creatures of gigantic proportions that have arrived accidentally on our planet from another dimension through some sort of portal. These creatures are stomping around causing all kinds of havoc, crushing cars, killing people, etc. I think that it's based on a Stephen King novel, but I don't know for sure. What's the name of this movie?
The creatures are kind of like dinosaurs, in the shape and size, land-dwelling, but their features unlike anything of this earth.
