This movie is one of 5 "Creature Features" made by HBO in 2001. The idea was to take a cheesy 1950s movie and remake it with better special effects. Stan Winston, the famous effects master, was one of the producers of this show. Not having seen the original, I don't know how this does as a remake, but it's a lot of fun on its own. A husband-wife team running a fake mermaid show at a carnival in Ireland are approached by a customer who seems crazy. He's very disappointed that the mermaid isn't real. They take him home to discover that he has in a tank in his house a real mermaid. The husband hatches a plot to steal the mermaid and take her to America to earn a fortune. The mermaid is convincing and beautiful, not to mention topless. The camera-work aboard ship is masterful. It evokes the claustrophobic closeness of a sailing ship below decks with close shots, tight framing and proximity of actors. There is also a subtle camera movement throughout these scenes evoking the sense of sea swells. I know this is an old trick, but I've rarely seen it done so well. There were long passages when I forgot it was happening, yet it contributed to the underlying reality of the movie space throughout. There are only a couple of surprises in the movie and both of them are homages to earlier great horror movies. I don't want to ruin it by giving them away, but you'll recognize them when you see them. There's not a lot of gore, by today's standards, but what there is is quite convincing. I don't think you'd want to let a sensitive 12-year-old see this movie. Also the mermaids are not portrayed as kindly creatures as they are in most movies.
