Alfred Hitchcock Presents:Jonathan (1956)

Gil Dalliford has an unnaturally close relationship to his father, whom he calls by his first name, Jonathan. "Every important moment of my life is a moment I had with Jonathan," he says. But after eighteen years of being a widower, Jonathan finds he's ready to settle down with a new wife. Before Gil even meets her, he declares his everlasting hatred for her. And that hatred only intensifies after his father dies. Of a heart attack, the doctor said. But Gil suspects foul play.
