Filming "White Mischief" on location in Kenya in 1987, Miles worked for the second and last time with Trevor Howard, who had a supporting role, but was by then seriously ill from alcoholism. The company wanted to fire him, but Miles was determined that Howard's distinguished film career would not end that way. In an interview with Terence Pettigrew for his biography of Howard, she describes how she gave an ultimatum to the executives, threatening to quit the production if they got rid of him. The gamble worked. Howard was kept on. It was his last major film; he died the following January.
