When Kelly breaks her bedroom window with a chair---to escape---the same creepy audio motif ("ooh, ooh" with a "shooting star" sound effect) that was repeatedly played at crucial, climactic moments in the horror-ish Of Ghosts and Angels (1980) can be heard. Jack Elliott and Allyn Ferguson provided the music score for both titles.
