My Brother's Keeper

Wealthy, retired tycoon Charles Stanford is sneaking around behind his brother's back with his wife when he finds out that his brother is terminal with cancer. Charles contacts a company that has had success fighting cancer by exchanging human and animal DNA. Instead of curing the cancer they create a chimera for Charles, a dog that carries much of his brother's DNA. Things go wrong.Wealthy, retired tycoon Charles Stanford is sneaking around behind his brother Winston's back with his wife when he finds out that Winston is terminal with cancer. Charles contacts a company that has had success fighting cancer by exchanging human and animal DNA. Instead of curing the cancer they create a chimera (animal/human hybrid) for Charles, in the form of a dog that carries much of his brother's DNA. This way Charles can still have a part of his brother that he really did love even though he cheated with his girlfriend. Things go wrong when the dog seems less like a new being and more like the reincarnation of his brother in an animal's body. This is a very real science. The University of Minnesota has dozens of pigs that produce human blood for a possible future method of producing blood for transfusions. Other companies have gotten fined for experimenting in DNA mixing that is unapproved.
