OHHHH MY GOD, Juno, You Have a GIANT Slit in Your Throat
Even though I didn't know what a caseworker was as a kid, Juno's inability to directly answer a question and her profound skill at disappearing whenever it was convenient made me uneasy whenever she was on the screen. After my second or third watch of the film, I realized she has a huge slit in her neck (right behind the frills, see?!) that oozes with smoke from the cigarette she's constantly holding. Dark implications aside, this hidden detail made me even more wary of the afterworld as a kid.
