I have no idea what they were thinking in this scene.
The really creepy stuff starts happening around :50. Enjoy.
2:30 is just trippy.
I have a bad habit of playing games late at night when it's dark, to improve my immersiveness of a game. I found that cutscene at around 3 at night and it scared the crap outta me. (Now I love it though)
Also, the Dunwich Building in Fallout 3 at 2-ish at night... not expecting Fallout 3 to pull out the creepy and scary all of a sudden.
