The Dark at the Top of the Stairs

Robert Preston plays the flip side of his eternally ebullient Professor Harold Hill in Dark at the Top of the Stairs. Preston portrays an early 20th-century harness salesman, fully aware that his product is rapidly becoming obsolete. He tries to compensate for his own lack of self-esteem by cheating on his patient wife Dorothy McGuire; Preston's "other woman" is played by Angela Lansbury. Meanwhile, daughter Shirley Knight falls in love with Jewish boy Lee Kinsolving, who kills himself in the face of relentless bigotry.
