The Dream Team is a 1989 comedy film directed by Howard Zieff and produced by Christopher W. Knight for Imagine Entertainment and Universal Pictures. It stars Michael Keaton, Christopher Lloyd, Peter Boyle and Stephen Furst as mentalhospital inpatients who are left unsupervised in New York City during a field trip gone awry. Jon Connolly and David Loucka wrote the screenplay.
Convinced that his patients need some fresh air and some time away from the sanitarium, Dr. Weitzman persuades the administration to allow him to take them to a baseball game at Yankee Stadium. Unfortunately, he accidentally encounters two crooked cops just as they murder another officer. The doctor then gets knocked unconscious trying to get away and is put in the hospital. The group is now stranded in New York City, forced to cope with a place which is often more bizarre than their sanitarium. One of the both comic and serious plot twists is that the inmates have to listen to Alberts baseball jargon in order to get clues as to what happened to Dr. Weitzman, because he is the only one who witnessed it he is just afraid to say it because of his catatonic condition. Two other running gags throughout the film are Henrys threats to report psychologically disturbing behavior of the other patients never realizing his own problems until near the end and Billys violent, unpredictable but ultimately harmless behavior in several different scenarios. A lesser gag is Jack, in his persona as Jesus Christ, causing a rousing sermon at a black church, only for the parishioners to come to their senses and expel him without any clothes, and the other three patients get Jack new albeit garish clothes from an army surplus store.After Dr. Weitzmans beating and coma, it is up to the patients to save their doctor from being murdered by the crooked cops. They end up having to both use and overcome their delusions and disorders in order to save the only man who ever tried to help them, with both the police and the killers looking for them. Three revisit scenes from their pasts Billy former girlfriend Riley, played by Lorraine Bracco, Henry his wife amp daughter, and Jack his former employer. As each patient does so individually, they each behave in a sane, clear manner, Henry genuinely missing his family, Billy wishing to pursue a stronger relationship, and Jack appealing to his boss that
