He's a man with too many things to do and not enough time to do them. Meanwhile, all he really wants to do is go sailing. It seems Dr. Leeds has perfected a way to create a flawless human clone in just a couple of hours. After a little convincing, Doug goes for it. Having more time to spend with his family, Doug should be completely happy.
Multiplicity is an actor's dream.
Keaton gets to be macho, sensitive, goofy and even normal, all by playing Doug Kinney. He's very funny in this comedy of errors, mostly playing off himself. Gratifyingly, special effects wizard Richard Edlund has woven together the various Dougs so well that it hardly seems like special effects at all, giving Keaton the room he needs to play all four roles convincingly. The film is just a setup for some slapstick, and there is no emotion behind the characters or the clones. A movie with an absurd premise can succeed if the characters react in a logical way.
