Ouija: Origin of Evil

The film was shot digitally, but director and editor Mike Flanagan, in order to add a retro feel to the film, added elements in post-production to give the appearance of a movie shot on film. Those include the 'cigarette burns', marks that appear every 20 minutes or so in the upper right corner of the frame, which were used to signal a change of reels for film projected.

In order to make the film appear more authentic for the time in which it is set (1967), cue marks, or "reel change" marks, are inserted at approximately every 20 minutes. However, the marks are oval when they should actually be circular, since this is a film presented in a 1.85:1 aspect ratio and not in a 2.39:1 aspect ratio. The only time the marks should be oval is if a film is projected with an anamorphic lens. On an anamorphic film print, the cue marks are circular, but the anamorphic lens makes the circle look like an oval when projected on a screen.

There is a post-credits scene with Lin Shaye.
