Laura Mulvey and Peter Wollen’s visually accomplished and intellectually rigorous Riddles of the Sphinx is one of the most important avant-garde films to have emerged from Britain during the 1970s. The second collaboration between Mulvey and Wollen, both of whom are recognised as seminal figures in the field of film theory, Riddles of the Sphinx explores issues of female representation, the place of motherhood within society and the relationship between mother and daughter.
