Multiplicity (1996)

Synopsis
In this zany comedy, Michael Keaton is Doug Kinney, a man with too many tasks and not enough time to complete them. When he feels too much pressure, his temper explodes with disastrous results. So when researcher Dr. Owen Leeds (Harris Yulin) offers him a somewhat unusual remedy for his problem, he gives it a try. Soon, a fully grown clone of Doug is delivered, complete with his memories up to the time of its "birth." Being in two places at once offers some advantages, but problems arise when Doug #2 can't handle the stress of overwork any better than the original. Perhaps Doug #2 could benefit from having his own helper. Versions of Doug multiply, each of them emphasizing some facet of his character, and complications multiply. For instance, having more of him around doesn't make life simpler for Doug's wife Laura (Andie MacDowell). ~ Clarke Fountain, All Movie Guide
