The Secret of My Success (1987)

Synopsis
Released at the height of his popularity on Family Ties and in the wake of Back to the Future and Teen Wolf, Michael J. Fox stars in this "country boy in the big city" comedy, directed by Herbert Ross. After making the move from Kansas to New York City, Brantley Foster (Fox) secures a job in the mailroom at his uncle's large corporation. Doffing any plans of working his way up the corporate ladder the old fashioned way, Brantley begins impersonating an executive to impress a high-ranking female co-worker, played by Helen Slater. Once his oversexed aunt enters the mix, Brantley finds himself juggling two identities, two jobs, and two women. ~ Matthew Tobey, All Movie Guide
