Some may not be aware that Paddy was pressed hard by Darryl F. Zanuck to be the scriptwriter for the 1958 film The Roots of Heaven, an adventure film made by 20th Century Fox, directed by John Huston and produced by Darryl F. Zanuck. The screenplay was by Romain Gary and Patrick Leigh Fermor and is based on Romain Gary’s 1956 Prix Goncourt winning novel The Roots of Heaven (Les racines du ciel).
The film had a fine cast and starred Errol Flynn, Juliette Gréco, Trevor Howard, Eddie Albert, Orson Welles, Paul Lukas, Herbert Lom and Gregoire Aslan. Paddy describes the negotiations and some of his time on set in Chad in letters to Debo Devonshire published in the book In Tearing Haste. I think Trevor Howard was drunk most of the time and Paddy appeared to be quite struck by the beautiful French actress Juliette Gréco. It was Errol Flynn’s last film
Set in French Equatorial Africa, the film tells the story of Morel (Trevor Howard), a crusading environmentalist who sets out to preserve the elephants from extinction as a lasting symbol of freedom for all humanity. He is helped by Minna (Juliette Gréco), a nightclub hostess, and Forsythe (Errol Flynn), a disgraced British military officer hoping to redeem himself.
