Wow interesting finds. The bottom one appears to be a picture of the dummy used for the head rotation scene, while the top one might be a Dick Smith makeup test? I don’t think either are frames lifted from the film at all.
Yeah, the top one is from the TFOG when the camera is running on Blair right after the head spin. It’s the scene where you can tell that the contact lenses are hurting Blair’s eyes because she keeps moving her eyeballs around and squeezing her eyes.
The second is definitely just another capture of the head spin.
