Reversal of Fortune is a 1990 American drama film directed by Barbet Schroeder that was adapted from the 1985 book Reversal of Fortune: Inside the von Bülow Case, written by law professor Alan Dershowitz. It recounts the true story of the unexplained coma of socialite Sunny von Bülow, the subsequent attempted murder trial, and the eventual acquittal of her husband, Claus von Bülow, who had Dershowitz as his defense attorney. The film stars Jeremy Irons as Claus, Glenn Close as Sunny, and Ron Silver as Dershowitz. Screenwriter Nick Kazan originally envisioned Austrian actor Klaus Maria Brandauer in the role of Claus von Bülow but was thrilled with Irons' performance. Irons earned the 1990 Academy Award for Best Actor for his performance in the film.
