The Thing That Couldn't Die

If only the movie were as entertaining as the poster.

The Thing That Couldn't Die is a 1958 B-Movie. The plot of this horror film largely centers upon a college-age girl named Jessica, along with her greedy aunt Flavia. Flavia runs a ranch that doubles as a bed and breakfast. Accordingly, there are several guests at the ranch.

Whilst digging a new irrigation line or well, aided by Jessica's dowsing ability, a fieldhand finds a chest. Due to the Greed of the Obviously Evil fieldhand, the chest is opened...and it contains not gold, but the severed head of a Very Evil Englishman. It turns out the Not Quite Dead Englishman, Gideon Drew, was beheaded for witchcraft during the expedition of Sir Francis Drake--but as part of his punishment, he's still alive. Can the Very Evil Englishman retrieve his body and live fully again? Better yet, can he pull it off for longer than thirty seconds?

Tropes used in The Thing That Couldn't Die include:

Anticlimax
Black Magic: An early debate on whether Jessica's ability to find things is this. She insists it can only be done of her own free will and she can't accept payment.
Cassandra Truth/You Have to Believe Me: Jessica's increasingly hysterical warnings to leave the chest alone go unheeded.
Corrupt the Cutie: Attempted.
Dowsing Device: Jessica uses a forked stick while 'water-witching.'
Dumb Muscle: Mike the farmhand, who's quite proud of how strong his hands are, but probably can't use his fingers to count with.
Evil Costume Switch: Jessica changes from a white dress to a black one after falling victim to the head's Evil Eye.
Fan Service: Two women sleeping in the bed? Oh yeah.
Flash Back: A lengthy one shows Gideon's judgment and execution.
Hypnotic Eyes: Gideon, in life and unlife, has the power to turn anyone who looks into his eyes Brainwashed and Crazy — unless they're wearing or wielding a holy symbol.
Large Ham: Gideon. Particularly impressive considering he spends most of the movie as a mute severed head.
Male Gaze: The last shot of the film is the pendant hanging in the deep v-neckline of Jessica's dress.
Non-Indicative Name: Once reunited with his body, Gideon dies just fine. Hell, he's even better at dying than your average villain.
Nice Job Breaking It, Hero: Gordon removes the cross from Jessica's neck...and ZIP! She's possessed!
Obviously Evil: Boyd.
Psychic Powers: Jessica...and Flavia as it turns out.
Reason You Suck Speech: After Gideon's head and body are reunited, he "thirst[s] for human blood". He goes around the room, rejecting each person's blood in turn and giving an insulting reason why ("your blood has dried up, and yours has turned to water", etc).
- Earlier, during the Flash Back, Gideon does some Facing The Bullets One Liners just before his execution.
Weaksauce Weakness: Faced with a servant of the Devil, whose sorcery is capable of bewitching even the strongest and most noble of souls and even managed to cheat death itself? Well, chuck a cross at him. It worked for Simon Belmont!
Why Don't Ya Just Shoot Him: Averted; one of the first things they do when Gideon is restored is shoot him. Unfortunately, he happens to be Immune to Bullets.
