In his autobiography, In Spite of Myself, Christopher Plummer makes the film shoot for Triple Cross sound more like a luxurious vacation than work. He was absolutely smitten with Young, his family, and their good friend, Lady Annie Orr-Lewis, who, Plummer recalled, constantly carried a Shih Tzu who she referred to as "My Little Sh*t." He also appreciated being housed at the old George V hotel because its long bar always featured a string of high-class call girls of various nationalities.
