The 'Burbs (1989)

Synopsis
Ward and June Cleaver have nothing on suburban couple Tom Hanks and Carrie Fisher. Together with their perfect son, Hanks and Fisher are so clean that they squeak. Thus, when new neighbors Henry Gibson, Brother Theodore and Courtney Gains begin evincing bizarre behavior, Hanks is slightly put out. Fisher thinks that Hanks is getting all worked up over nothing. Hanks and his fellow suburbanites endure all sorts of slapstick misadventures in the vain hope of getting "the goods" on the newcomers. ~ Hal Erickson, All Movie Guide
