Subject Two is a 2006 American film directed by Philip Chidel and starring Christian Oliver and Dean Stapleton.

Adam, a medical student, is lured to a cabin far from civilization where he volunteers to be repeatedly killed and reanimated by Dr. Franklin Vick, through use of a mysterious serum.

While "Subject Two" as he is initially successful, he begins to experience violent seizures and excruciating pain, begging Vick to kill him or committing suicide several times.

His eyes turn snow white, and, to compensate for the gradual loss of his sense of self, he becomes violent and depressed, going so far as to kill a hunter that accidentally shoots him rather than risk him exposing the project.

Thinking that he had accidentally killed Dr. Vick, Subject One assumed his identity to continue the work, but finds that the serum was initially perfect, and it was only his tampering that gradually changed Adam.
