Watch VoirFilms. Michael White might just be the most famous person you’ve never heard of. A notorious London theatre and film impresario, he produced over 300 shows and movies over the last 50 years. Bringing to the stage the risqué productions of Oh! Calcutta!, The Rocky Horror Show and to the screen Monty Python and the Holy Grail, as well as introducing Merce Cunningham, Pina Bausch and Yoko Ono to London audiences, he irrevocably shaped the cultural scene of the 1970s London.
