Multiplicity

Doug Kinney (Michael Keaton) works in construction in Los Angeles and his job is constantly getting in the way of his family. Working on a new wing of a scientific facility, Doug meets Dr. Leeds (Harris Yulin), a friendly scientist who has successfully developed a method for cloning humans. He is introduced to Dr. Leeds' clone as proof. Sympathetic to Doug's troubles, he clones him so the clone can take over for Doug at work, while the original tries to spend quality time with his family. The clone, called "Two" (although he calls himself "Lance"), has all of Doug's memories and knowledge, but personality-wise is an exaggeration of Doug's masculine side.
