Paranormal activity movie

Hello hello! for all the horror fan out there, an awesome movie seems to exist! On september 2009 a screening was help in California entitled "Paranormal activity". You can see in the trailer what happened! The trailer looks so promising and not at all fake! No tones of gore and splatter or fountains of blood, no CGI monsters, ghouls and shit like that! Just a couple of cameras and two actors.
