John Fowles' debut novel The Collector has been adapted several times for theater stage and big screen, most notably by William Wyler, later by Mike de Leon for a 1986 feature--Bilanggo sa Dilim (Prisoner in the Dark) shot on video.
Comparing the two productions can be instructive: Wyler's is a smoothly executed Hollywood production with a fairly gripping finale; de Leon's feels more subdued, understated, unnervingly autobiographical.
