Tower of Evil (also known by the titles Horror on Snape Island and Beyond the Fog) is a 1972 British horror film directed and written by Jim O'Connolly and starring Bryant Haliday and Jill Haworth.

After seeing the male body it was attached to, they decide to enter a lighthouse to investigate.

The shocked Penny eventually starts talking and remembering how her friends arrived.

After hearing about this, some scientists decide to visit the Island, which is loaded with gold and Phoenician treasures.

The team, consisting of five men and two women, sets out on the Sea Ghost, which is captained by the surviving seaman.

She investigates, and looking through a wall, she sees Saul, rocking the corpse of his dead wife.

He finds Nora, who runs to the top of the lighthouse where Saul throws her off onto rocks.

Rose and Dan, one of the men, stay with the treasure while the captain, the Doctor and the other man go looking for Saul.

As he burns to death, the house and cave catch on fire as Saul had it rigged to.

Rose escapes and the two surviving men leave the cave to watch the house and its dwellers burn.

Gordon was then introduced by Herman Cohen to Jim O'Connolly (the two men had made Berserk!

[5] Gordon says the British unions protested the importation of American actor Bryant Haliday to play a role.

[5] Gordon says Mark Edwards was recommended to him by James Carreras off the back of Blood from the Mummy's Tomb.

[7] The Monthly Film Bulletin wrote: "Apart from the novelty of its double climax, this is predictable, youth-oriented horror of the "I thought I heard something" school, with a group of unusually attractive, pot-smoking, sex-starved archaeologists stranded on the archetypal accursed isle.

As much energy is expended on the self-conscious nudity and violence as on the suspense, but dialogue and performances are anyway equally unconvincing.

[citation needed] The Terror Trap horror review rated the film positively, calling it "A surprisingly adroit little British slasher, Tower of Evil is a revelatory sleeper.".
