the evil below start on the strait of san sebastian 1683 a the 17th century treasure ship the el diablo sink in a violent thunderstorm . jump to the strait of san sebastian present day where two diver be explore the beautiful underwater coral reef that be rich in wildlife and the come across the sunken wreck of the el diablo and explore it but be attack and kill by something that look like a vicious eel . captain max cash ( wayne crawford ) own and run a boat for hire name the vagrant viking which caters for tourist who want to fish and dive and generally explore the island . sarah livingstone ( june chadwick ) be an art teacher who dive for treasure a a hobby ( well we all have to do something to pass the time right . ) and she hire max and his scantily clad assistant tracy ( sheri able ) so she can try to locate the el diablo and get rich . talk of sunken treasure excite some of the more unscrupulous member of the local community and a they dodge the criminal and thug it be bring to max and sarah attention that the el diablo have a sinister past and a past that supposedly still leave it supernatural legacy behind even now . direct by jean claude dubois and accord to the imdb with a little help from star crawford although the version i saw only list dubois and i think the evil below have some potential and be a bit different but unfortunately that not enough to save it from sink to the bottom of the sea like a stone . the script by arthur payne start off ok with the two diver be kill by some sort of sea creature but this opening be never refer to again and the creature be never see again and there be no more supernatural killing . the evil below then suffers from a serious and terminal case of identity crisis and it doesn not seem to know what it want to be a it chuck bit and piece of various genre in there from underwater adventure and horror and action and thriller and crime and it even have time to throw in a little murder mystery and religious nonsense as well . a a result the evil below feel very bitty and fragment and since the best scene in the entire film be the opening sequence i find myself sit there become more and more frustrate at the lack of any consistent horror a it go downhill rapidly and the fact we never see the sea creature thing again . the evil below be dull and slow and uneventful and predictable and silly and lack any sort of charm or intelligence and in short the evil below doesn not do anything right that a good film should . director dubois fail to liven thing up although he obviously shoot plenty of underwater wildlife material a at time i think i be watch a national geographic documentary with all the shot of fish and coral and the wildlife in general . forget about any gore and some blood stain water and blood coughing be about as gory a it get i be afraid . technically the evil below be very basic and it bland and totally forgettable apart from nice underwater photography of fish . this be point and shoot stuff and a a whole the production value be very low and even the place where this be shoot doesn not look very sunny or appeal . the acting be poor and but then again do you expect anything else . the evil below be a poor film and it basic story be all over the place and it can not decide what it want to be and a a result it end up be a mess . add that to the low production value and the fact there no gore here and absolutely minimal horror content you have a film that be probably best avoided unless your absolutely desperate and even then surely there be good way to spend 90 plus minute of your life .
