Agency tackles the question of the efficiency of media manipulation. An unscrupulous advertising agency, in league with equally untrustworthy political campaign manager Robert Mitchum, plants subliminal messages in its TV commercials. Just as Vance Packard warned in the 1950s expose The Hidden Persuaders, these hidden messages persuade the viewers to vote for Mitchum's candidate. Given the potency of the the film's premise, it's disappointing to watch director George Kaczender handle the material (based on a novel by Paul Gottleib) is so cut-and-dried a fashion. But Mitchum is good, as are his costars Valerie Perrine, Lee Majors, Saul Rubinek and Alexandra Stewart.
