Hi, apparently this scary score has never been released (in the mood of Kaproff's masterpiece : When a Stranger Calls (1979))... but maybe someone has information or bootleg score (from the blu ray source) ?
by any chance...
thx

*bump* I tried to rip the score from the Bluray but it doesn't seem to be a real 5.1 upmix, all the center channel audio is across all the other 4 channels making a clean rip impossible.
