"Dove" . Cheesy but a good flick and true story although "Hollywoodized". Available on Netflix and probably Amazon.
"And The Sea Will Tell", made-for-television movie based on the book and real life events
. I have not been able to find it for rent. Disturbing book but engrossing read.
"Deep Water" the story of Donald Crowhurst, documentary that is again disturbing but fascinating. Available on Netflix.
