Richard Egan's (Ken) impassioned speech to his wife about her disgraceful bigotry was so powerful that an entire packed audience at Radio City Music Hall gave it an immediate standing ovation.
Initial considerations for the role of Helen Jorgenson included Teresa Wright and Olivia de Havilland.
Max Steiner's main theme for this film is probably his best-known after his "Tara Theme" for "Gone With the Wind." As with "Tara's Theme," it has remained a favorite ever since, with several charting recordings. Percy Faith's version (American Columbia: 1960) went to Number 1 on the Billboard Hot 100 chart in 1960, remaining in that position for 9 weeks, becoming both the Number One Instrumental Hit of the Rock Era and the first instrumental to win the Grammy for Record of the Year. Other charting versions were by Billy Vaughn (Dot: 1960, peaking at #2), the Lettermen (Capitol: 1965, using Mack Discant's lyrics and peaking at #16), and the Ventures (Liberty: 1969, at #83). Faith himself re-recorded it, shortly before his death in 1976, in a disco arrangement entitled "Summer Place '76."
The house where Ken (Richard Egan) and Sylvia (Dorothy McGuire) lived toward the end of the film is an actual private residence that was built by Frank Lloyd Wright in 1948. It still stands today on Scenic Road in Carmel-by-the-Sea and is a prime feature in local tours.
