There was a macintosh point and click adventure game released in the 1990s called "ghosts" which starred Christopher Lee as a narrator. It involved navigating a haunted house, learning about encounters with ghosts and featured full narration and FMV.

I used to own this title but realised I sold my copy off wiht all my mac stuff before I made a disk image of the CD for uploading. D'oh!

It was a Mac/PC hybrid game but I don't really mind which version gets uploaded.

Here's the link to it on Amazon:
