Over at the Glom for the best
footnote ever:
Compare INVASION Of THE BODY SNATCHERS
(Walter Wanger Productions 1956) (depicting pod people as merely pointing
silently at humans that had not been replaced) with INVASION Of THE BODY
SNATCHERS (Solofilm 1978) (depicting pod people as pointing and emitting shrill,
piercing screams to identify humans that had not been replaced).
The search for a way to sneak in a pinpoint cite to that one
begins . . .
For those craving a visual, see below. Surely, a spoiler warning is
unnecessary for this classic, but this gives away the ending.
