Mutants in films have been around for years now. The technical definition found from Wikipedia itself states : "In biology and especially genetics, a mutant is an organism or a new genetic character arising or resulting from an instance of mutation, which is a base-pair sequence change within the DNA of a gene or chromosome of an organism." That means it's a new entity that becomes so by DNA or genetic experimentation. In horror films, the experimentation always seems to go wrong.
Mutants as a film's monster, or antagonist has always been a hit. Why? They are, when you really think about it just human beings. What is it about mutants that have terrified audiences around the world for decades now? For example the original The Hills Have Eyes (1977). When this movie was released it scared millions. The mutants in the film alone were so hard to look at, some people couldn't sit through the entire film. What made this film even more disturbing is that in fact it was based off a true story. Alexander Sawney Bean was known as the leader of savages that went on the rampage of killing over 1,000 people in the hills.
The Hills Have Eyes however did not stop in the 70s. It released a sequel in 1984 titled The Hills Have Eyes Part II. And almost 20 years later, a remake of Wes Craven's original film was out, and prepared to scare a whole new generation of movie goers. Which is exactly what The Hills Have Eyes (2006) did, as well as released a sequel, The Hills Have Eyes 2 (2007). As much as all true horror fans loved the original, they certainly couldn't deny that the mutants in these new films were remarkably grotesque.
Speaking of remarkably grotesque we have one of the goriest, gaudy, raunchy, yet entertaining series Wrong Turn. These movies are either loved or hated, so bare with me. Wrong Turn's mutants increased the level of terror and sick. They not only looked extremely hideous, they did and said terrible, nasty things as well. Wrong Turn literally turned the mutant genre into a whole new game. Simply because it was not only for terror, but to make the audience's stomachs turn. Wrong turn as a whole has five films, and is about to release the sixth next month.
Mutants from these two series alone proves that there's nothing quite like them. As humans ourselves, to see the possibilities of what our bodies and faces can become or do is terrifyingly realistic in these movies. Based off our own past, we have experienced extreme, intense, major radiation poisoning, causing one to deform or become extremely ill. It however has never been exposed and shown in such a way as these movies have done. Which is why I commend these series as successful human mutant horror films.
