I don't know about terrifying, but I recently watched a really suspenseful film called Primer. It's about two engineers who accidentally make a time machine, and the ethical and moral decisions that come with such a device.

The film wastes no time with exposition; it almost as if you're eavesdropping on these people's conversations. If you haven't seen it, I highly reccomend it.
