There's another trailer for the US remake of Pulse online, and this one gives away a biggie. I'm not sure if it's big in terms of the US version, but it was good not knowing this when you saw the original.

However, if you want to see it you can catch all three trailers over at IFILM [QT:RP:WMV] through Jo Blo, and you're looking at Trailer #3.

I think it looks pretty good, and they seem not only to have captured the feel of the original but also improved on it with some of the spooky ghosts. This might actually not be that bad, although some of the cast give rise to suspicion for me.
