In 1971, Pakula released the first installment of what would informally come to be known as his "paranoia trilogy". Klute, the story of a relationship between a private eye (played by Donald Sutherland) and a call girl (played by Jane Fonda, who won an Oscar for her performance), was a commercial and critical success. This was followed in 1974 by The Parallax View starring Warren Beatty, a labyrinthine post-Watergate thriller involving political assassinations. The film has been noted for its experimental use of hypnotic imagery in a celebrated film-within-a-film sequence in which the protagonist is inducted into the Parallax Corporation, whose main, albeit non-ostensible, enterprise is domestic terrorism.
