East of Elephant Rock is a 1977 British independent drama film directed by Don Boyd and starring John Hurt, Jeremy Kemp and Judi Bowker. It was Boyd's second feature film following his little-noticed 1975 Intimate Reflections. Like William Somerset Maugham's 1927 play The Letter and two subsequent film adaptations, its narrative content depended on the 1911 Ethel Proudlock murder in Kuala Lumpur, Malaysia, which became a cause célèbre scandalising British colonial society and which had been featured in a Sunday Observer article as recently as the year before. Boyd, drawing in part on his own experience of growing up in an increasingly dysfunctional family in Kenya during the Mau Mau rebellion, wanted to tell a story about the decline of the Empire and the surrender of responsibility. In the event his project was for the most part ridiculed but the film did draw warm support from the film director Bryan Forbes.
The film is set in South East Asia in 1948 in an unnamed British colony. Embassy secretary Nash is having an affair with a native woman. He takes as mistress the wife of a plantation owner with fateful (and fatal) consequences.
The film is treated at length in Alexander Walker's book National Heroes: British Cinema in the 70's and 80's. It was filmed on location in Sri Lanka on a budget of just £100,000.
The film received an extraordinarily hostile UK press and there were suggestions that Boyd had 'ripped-off' William Wyler's classic film noir The Letter. Boyd responded, not implausibly, that he simply hadn't seen Wyler's film but he certainly knew of the Proudlock affair.
