True thriller.
Neat idea. Here's what I can figure from the trailer...
"Mmmph mph mmmph mmph"
"Mmmph mmmph mphh mphhh hiss"
"Mmph hiss mmph mmmmph the call!"
"Mmmmmph mmph mmph."
"Mmph mmmmph mmph terribly wrong."
Then some kid decides to play with his webcam for a minute or two.
Sounds like a hit.
