I just watched the (gory) thriller P2. It is about a girl who gets kidnapped in a parking garage on level P2 on Christmas eve. Not a bad flick.
In one scene, the heroine makes it to a phone and dials 911. She is put on hold. I imagine they did that for the effect, but I don't think they realize just how realistic that could be.
BTW, all the more reason to a) carry and b) have a flashlight.
