It actually incorporates some old footage from like five years ago with more recent footage of me sitting there looking unsettled. Unfortunately not in the basement but in the bathroom...
I actually used some red paint on my face to make it seem if not bloody, then at least bruised. In the end I used a take (and colour corrected it) that wasn't very well lit so it isn't visible at all.
The old footage is from when I had just got the camera and is basically me filming while I exit the elevator to my old apartment and enter it. All the ambient sounds in the video are real from the footage available. Except for the chainsaw.
I probably should have done some audio stuff to the chainsaw to make it sound less... detached but what the hell.
