Think you know everything bout movies???? help me out! then

Oookay here is the issueI already tried googlin for 3 hours it doesn't work me and my best friend that for some reason is afraid of horror films but LOVES to watch them want to see a movie, I suggested her one but I don't know the name neither does her but I DO know what's it about strange isn't it?

The thing is that I saw the trailer while I was at the movies back on 2009 here is the thing

There is a witch of some sorts and she is only able to harm you IF YOU SCREAM so if you do not scream all is good but she'll do whatever it takes to make you scream for example there is a part in the trailer where the people are walking and one of the guy gets like trapped by the witch and she opens her mouth and yells but the guy is like so scared but can't scream then he falls and some girls goes

EEEKKKK (screams)

and then the witch takes her

I know it's strange but I'm really want to find it the Name or the link to the trailer so I would Appreciate help from you guys in the OT.

Remember it will only happen IF YOU SCREAM

It's called Dead Silence. Parandrus

Dead Silence. Made by the guys who made Saw. I hated it but it's pretty crazy, especially the ending.

just saw the trailer, whoa it's scary
