The answer to this question is simple; Dr. Abigail Tyler from the science fiction movie The Fourth Kind is NOT real. This can be confirmed by visiting the movies page on IMDB and viewing the actors and actresses list.
It states there that the real Abigail Tyler was indeed also played by an actress, and not Abigail Tyler, as you would expect was she a real person.
The Fourth Kind is a science fiction horror movie and is based on the expansion of J. Allen Hyneck’s classification of close encounters with aliens. The film was a huge success earning over $47 million worldwide from a $10 million budget.
In 1972 a scale of measurement was made for alien encounters, whereby the encounter of the first kind is when a UFO is sighted, an encounter of a second kind is when evidence is collected, an encounter of a third kind is where contact is made with the aliens and the fourth kind is abduction.
The film claims to be based on actual events happening in Nome, Alaska in the year 2000 whereby a number of the population has been reported missing every year, and nobody knows a reason why. It is after the mysterious death of her husband that Psychologist Dr. Abigail Tyler decides to use hypnosis on traumatized patients which she also videotapes, and discovers that she too, may have also been abducted.
The film is filmed in two different ways; dramatization whereby actors play the individuals involved and video footage of the patients being hypnotized. Dr. Abigail Tyler is shown being interviewed throughout the film; however this is just a part of the story as she is played by an actress.
Although based on real disappearances, The Fourth Kind is no more real than The Blair Witch Project or Cloverfield.
