With Francine Stock. Slumdog Millionaire and The Full Monty writer Simon Beaufoy tells Francine Stock about The Battle Of The Sexes and why it wasn't love all between tennis players Billie Jean King and Bobby Riggs, when he challenged her in 1973 to prove that a woman could play as well as a man. Beaufoy reveals why he would make the film much harder hitting now in the light of the revelations of sexual harassment in the film industry and shares his experiences at the hands of Harvey Weinstein. Neil Brand explains how Alien changed the sound of science fiction in his new series, Game Changers. Sandra Hebron and Briony Hanson slug it out to get their chosen directors, Yasujiro Ozu and Francois Ozon, for a place in The Film Programme's A to Z of film-makers.
