Towers began producing feature films in 1962, sometimes writing the screenplay. Towers filmed in various countries such as South Africa, Ireland, Hong Kong, Bulgaria and others. A number of his films and scripts were based on the works of
Sax Rohmer, such as
Sumuru and the popular
Fu Manchu series of five films starring
Christopher Lee. He also adapted the novels of
Agatha Christie (
And Then There Were None and the
Miss Marple series), the
Marquis de Sade, and the works of
Edgar Wallace. Towers produced three separate film versions of
And Then There Were None, each set in a different locale. He worked a number of times with
Nat Cohen and it has been argued Towers made his best films with Cohen. He frequently collaborated with director
Jesus Franco during the late 1960s and early 1970s. Towers had a hand in writing and/or producing numerous films directed by Franco, including
99 Women (1969),
The Girl from Rio a.k.a.
Rio 70 (1969),
Venus in Furs (1969),
Marquis de Sade: Justine (1969),
Eugenie… The Story of Her Journey into Perversion (1970),
The Bloody Judge (1970), and
Count Dracula (1970). Franco also helmed the last two Fu Manchu films
The Blood of Fu Manchu (1968) and
The Castle of Fu Manchu (1969). Towers made several films starring
Shirley Eaton. In a letter from the New York literary agency Albert T Longden Associates, discussing the Sax Rohmer estate, reference was made to Towers producing a sixth Fu Manchu movie,
The Children of Fu Manchu, for release in 2009; if the project existed, nothing came of it. ==Death==
