InAlienable is a 2007 science fiction film with horror and comic elements, written and executive produced by Walter Koenig, and directed by Robert Dyke. It was the first collaboration of Koenig and Dyke since their 1989 production of Moontrap. Koenig said that "the story really involves that relationship between the human being and the alien. At first, it's assumed that the alien [is] a parasite growing in a host, but because it has some of the human DNA, it's significantly more than that. Even though it comes from another world, it's a part of our world. Really, it's a love story."

Plot

Dr. Eric Norris remains wracked with guilt after a terrible tragedy that cost him his family, and when he learns that an alien parasite is not only growing inside him but shares his DNA, he develops a fiercely paternal bond with the creature. The alien "might regenerate into a surrogate son to replace his own child who was lost years earlier." Koenig plays the antagonist, a scientific research institute administrator who dislikes Norris because he had been mutually in love with Norris's wife, who died; he blames Norris for his own now bleak life and enjoys insulting him. Norris, new love interest Amanda, and attorney Howard Ellis must defend the new child, Benjamin, from being imprisoned by government forces or, worse, destroyed. The courtroom trial covers such issues as habeas corpus and miscegenation.
