sentences:  In 1967, the novel was made into a film, "To Sir, with Love", starring Sidney Poitier and Lulu, and the film's title song became a number-1 hit that year.The setting for the film was changed from post-war London to the "swinging sixties", and, notwithstanding its success, Braithwaite had ambivalent feelings towards it, as he admitted in an interview with Burt Caesar conducted for a 2007 BBC Radio 4 programme entitled "To Sir, with Love Revisited" (produced by Mary Ward Lowery).Also in 2007, the novel was dramatised for Radio 4 by Roy Williams and broadcast in two parts, starring Kwame Kwei-Armah.
