the dream team is a thoroughly entertaining comedy featuring four loveable characters who just happen to be slightly insane .
billy , played by michael keaton , is an extremely temperamental mental ward patient whose short fuse and violent tantrums tend to get him in trouble .
christopher lloyd portrays henry , an obsessive - compulsive who requires that everything be neat , orderly , on schedule , and by the books .
he thinks he 's a doctor
so he walks around wearing a suit and carrying a clipboard on which he constantly scribbles notes and files reports .
jack , played by peter boyle , thinks he 's jesus .
and finally , there 's stephen furst as albert ,
a chubby catatonic who speaks only in baseball and television phrases .
the dream team follows the misadventures that beset the four - some when their psychiatrist , dr .
weitzman , takes them out of the hospital for a field trip to yankee stadium .
during a pit stop , they get separated from weitzman and are left to fend for themselves in manhattan .
the movie 's charm derives mostly from the camaraderie and chemistry between its delightful cast .
the four leads in the film play off each other quite effectively ; they never miss an opportunity to argue , bicker , or insult one another .
henry and jack , for example , fight over who 's going to get to ride in the front passenger seat on the way to the game .
the actors in the dream team have a lot of fun with their characters and with each other .
michael keaton is
well cast
as billy ; he gives his cynical character considerable complexity .
as the divinely jack , peter boyle succeeds in keeping his one - dimensional character funny and fresh .
although stephen furst 's catatonic character is cliched , the actor makes him sympathetic and endearing .
while keaton , boyle , and furst are good , it 's christopher lloyd who really makes the movie special .
lloyd gives yet another outstanding comic performance .
his body language ( for example , the way he walks ) and his facial expressions are perfectly suited to his compulsive character .
lloyd 's brilliant performance yields a pathetic , moving , and memorable character .

the characters are so appealing that you can excuse the film for its often outlandish and unbelievable plot .
