I'm so glad that you enjoyed
Lisa too. According to Dolores Hart's memoir, she and Stephen Boyd became quite close during their intense work together on this film, with a bit of a romantic attachment formed between them. He visited her early in her days in the convent, but could not reconcile himself to her choice, though she remained fond of him. I like Boyd's work early in his career, particularly in this movie,
The Man Who Never Was, Abandon Ship!, The Best of Everything, Seven Thunders and
The Third Secret. After that, he and Hollywood changed, but not necessarily for the better.
Sadly, Jan de Hartog's books are rarely read now. He was a wonderful writer, full of empathy but with a wry detachment from cant--perhaps due to his long experience in peace (he became a Quaker) and war (he was in the Dutch Resistance). Despite everything he saw, he was also capable of considerable hope and wit about human nature, which may have been one reason why he almost won The Nobel Prize. BTW, de Hartog also wrote
The Four-Poster, a lovely play about a long marriage that ought to be revived on stage (On screen, real life (turbulent) couple Rex Harrison & Lili Palmer played the roles in 1952). The Four-Poster was also a musical as "I Do! I Do!" in the 1960s with Robert *sigh* Preston & Mary Martin.
I love Philip Dunne's work as a screenwriter and a director too, though he was never completely satisfied with the latter pursuit, which he described as "a lot of fun," though he knew that the script was everything. Dunne wrote a good autobiography,
Take Two: A Life in Movies and Politics, though he was very generous in his memories. He was also profiled and interviewed by Tina Daniell in Patrick McGilligan's
