Synopsis by Mark Deming
A scientific experiment gone wrong causes a man to become his own evil twin in this made-for-TV thriller. Marty Stillwater (Stephen Baldwin) would seem to have it made; he has a beautiful wife, two loving daughters, and a great career as a bestselling mystery novelist. However, it soon seems there's a fly in the ointment -- or, more accurately, some of Marty's blood. An evil but brilliant industrialist's son is working with rogue scientists to create an army of superhuman mercenaries through DNA cloning who will do his bidding and conquer the world. However, a sample of Marty Stillwater's blood is used for the cloning process instead of DNA from the pumped-up warrior the would-be world leader had in mind. The clone, named Alfie, has murder on its mind, just as the scientists wanted, but it looks like Marty, talks a bit like Marty and even seems to share a few of Marty's thoughts -- enough of them that it finds Marty's home and moves in, and before long his family is wondering why Dad is displaying a split personality. Dean Koontz's Mr. Murder was originally shown as a two-part miniseries on ABC in April 1999.
