Summer Switch (1984)

Synopsis
Often cited as a rip-off of such "parent-kid personality switch" films of the 1980s as Like Father, Like Son and Vice Versa, this ABC Afterschool Special actually predates those projects by several years. Summer camper Ben Andrews (Scott Schwartz) would like to be a grown-up. Ben's father, Bill Andrews (Robert Klein), a harried movie executive, yearns for the carefree days of childhood. Inevitably, Ben and Bill switch personalities, with uproarious results. Amazingly, no one seems to notice the switch, not even when 12-year-old Ben puffs away on a pipe while heading a movie conference, and middle-aged Bill totes a teddy bear all around summer camp. (One would think that the overacting of both stars would rather give the game away, but we shouldn't be seeking logic here, should we?) Summer Switch is based on a novel by Bruce Rodgers. ~ All Movie Guide
