Horror film trailers

I chose the film trailer for The Unborn, as from the beginning of the trialer it is obvious that it is a horror as, what appears to be a babysitter is sitting on a sofa on the phone, when creepy sounds are heard from upstairs, through the baby monitor, she finds the child and he attacks her, saying the line 'he wants to be born now'. the trailer shows creepy kids, weird occurances and visions, its fast - paced, freaky, the woman has to resort to exorcism, as all hell breaks loose, can she be saved from the spirit of her unborn twin.
