YMMV / Murders in the Zoo

• Complete Monster: Eric Gorman is a millionaire zoologist and big game hunter who is homicidally possessive of his wife Eveleyn. Introduced sewing closed the mouth of a colleague who kissed Evelyn and leaving him out in the wilderness to be slaughtered by wild animals, Eric plots to dispose of Roger Hewitt after he catches Evelyn's eye and fatally poisons him with mamba venom at a feast. When Evelyn threatens to expose his crimes, Eric tosses her into a pit to be torn apart by alligators with not an ounce of hesitation. Eric quickly poisons Dr. Woodford afterwards once he catches onto Eric's murders and tries to kill his assistant in a fit of rage after she saves Woodford's life. Even in spite of his charms, Eric is a senselessly violent psychopath whose crimes shocked audiences back in the 1930s and continue to stand out in depravity years later.
• Nightmare Fuel: Murders in the Zoo was noted to be particularly intense and grisly for the time period—it was a pre-Code film, but one that had no qualms with utterly horrific and in-your-face imagery, the most infamous of which is the opening scene where a man's mouth is literally sewn closed.
