Inissible Evidence is a 1968 British drama film directed by Anthony Page and starring Nicol Williamson and Jill Bennett. John Osborne wrote the screenplay, adapting his own 1964 play Inissible Evidence. The film portrays the collapse of an angry but sad man who cannot maintain decent standards in his life and antagonises everybody. As with other Osborne plays, it is possible to see his descent as representative of his class, culture and nation.
