Arnold Schwarzenegger's "The Sixth Day." In that film, ...
... visits a pet-cloning shop where he can order a clone of his family dog, which had suddenly died.
The scene from the movie is a fabulous exaggeration of what a company like GSC offers. There is no instant cloning while you wait. You can't tinker with your pet's DNA to make your cat or dog smaller, larger, fluffier, or less likely to shed.
But that fictitious pet store, called RePet, was selling the same promise the pet shop for clones is peddling - to regain an emotional connection to a pet.
