a early 70 horror flick go and tower of evil ( a. k. a horror of snape island ) have a great than expect amount of sex and gore . unfortunately and the script be pretty stupid and the performance be generally bad and ruin what might have be a decent little chiller . some of the line the actor have to work with be hopelessly silly and and the number of time character go wander off alone ( even after they have establish there a madman on the loose ) beggar belief . what particularly disappointing be that the plot be just outlandish enough to have make for an unusual and effective horror yarn . the opening sequence be actually promising . two sailor and john gurney ( george coulouris ) and his son hamp ( jack watson ) and search around a fog shroud island and stumble upon several dismembered naked body . then and john happens across a living naked woman and but she be so startle by his arrival that she mistakenly stab him . the story move forward and we learn that the survive woman from the opening scene have be charge with the murder of her friend and but a private detective name brent ( bryant halliday ) have be hire by her parent to find out if someone else could have do it . brent join an archaeological party who be about to set off to the island in search of a phoenecian treasure . once there and the archaeologist soon learn that their life be in grave danger and a they be pick off one by one by an unknown killer . tower of evil have become a cult film and probably because it so bad that in some way it perversely good . ther be some attempt at atmosphere and suspense and though most opportunity for a jolt be clumsily edit and lessen the shock factor . in halliwell film guide and the film be dismiss a an unoriginal little shocker and but unoriginal be probably the wrong word ( how many time have you hear of archaeologist hunt for a phoenecian hoarde off the english coast and and be victimise by a psycho . absurd and yes . unoriginal and no ) . i can not imagine this film be of particular interest to most viewer and but if you like 70 british horror and or be interested in how sex and gore have evolve over the year in horror cinema and then it may be worth catch .
