"I'll show you who I am and what I am!"
- Griffin's ferocious temper and megalomanic insanity, coupled with his invisibility, produces a frighteningly unpredictable package. He ends up with the highest body count of any of the classic Universal Horror monsters, as well as most horror movie slashers, most of which he does for no reason at all.
- The death scenes themselves are increasingly nightmarish:
- First, he strangles the constable nearly to death, and then finishes the job by bashing him in the head with a stool.
- Later, while a search party is looking for him near a cliff-side, he takes the liberty of pushing two of them off.
- He sneaks into a railway tower and bludgeons the switchman in the head with a lamp. It is left unclear if the man survives.
- He then tops all of the previous crimes by derailing a train, which apparently kills a hundred people.
- Finally, there is the death of Kemp, who he chokes, ties up, and then throws into a car, which he then sets in motion, resulting in a deadly crash.
- Worst of all, it's implied that he planned to do all this; in a conversation with Kemp, he lays out his plans to bludgeon a switchman with his invisible hands and 'derail a train or two', and later on threatens Kemp with the exact time and details of his impending murder.
- The death scenes themselves are increasingly nightmarish:
- Really, the whole film is made of Paranoia Fuel, as it milks the implications of Griffin's capabilities for all they're worth. The country is in such a panic that the British government is on the verge of declaring a state of emergency because of one man's nigh-unstoppable rampage.
- Not helping matters is the many instances of Black Comedy scattered throughout the film. Theoretically, this should add some levity to the film, but the resulting Mood Whiplash ultimately creates a sense of unease that never truly lets up until Griffin is finally defeated.
- In general, the concept of an invisible person wanting you dead is enough reason to incite paranoia. Especially when he describes what time he promises to do so and how he believes you'll die, as Kemp finds out.
