John Paddy Carstairs

The son of actor Nelson Keys, and the brother of director Anthony Nelson Keys, Carstairs changed his name to his mother's surname in order to avoid the appearance of nepotism. He directed 37 films in total. He had a long association with the character of Simon Templar (the character's creator, Leslie Charteris, dedicated the 1963 book, The Saint in the Sun to Carstairs). Aside from directing the 1939 Saint film, The Saint in London, he also directed two episodes of The Saint in the 1960s, making him the only individual (other than Charteris himself) to be connected to both the Hollywood film and British series of The Saint. Carstairs directed many British comedies including Norman Wisdom's first six films. Filmink magazine argued Carstairs had "a style as recogniseable as any British auteur – we’re surprised more academics don’t discuss him."

Carstairs died of a heart attack on 12 December 1970, aged 60.
