Lost Raven (2007)

After learning that he has contracted the HIV virus, attorney Zak Raven leaves his practice behind to set forth on a mission of relaxation-- until his peaceful trip goes wildly astray, leaving Zak shipwrecked on what he thinks is a deserted island with only the words in his own journal to keep him company. Unknown to Zak, four miles below the surface secretly hides a government experimentation center where scientists are playing God by trying to artificially evolve a human based species that can survive evacuation missions in deep space. Within 900 years, earth will be dealt a deathblow by a mountain-size asteroid. However, so far they have only achieved creating living abominations. Zak and these creatures are on a collision course, and he must rise to the challenge!
