If you are thinking about an artificial boy named "Conrad", perhaps the movie in question is the 1985 TV flick
Konrad, starring Polly Holiday (from the series
Alice), Ned Beatty, and Max "ALF" Wright. The storyline involves a vat-grown eight-year-old who is delivered to the wrong address, and naturally he and Ms. Holiday bond, and must fend off the efforts of Mr. Wright, the factory owner, to reclaim him.
