British lawyer and socialite Claus von Bulow’s 1982 conviction for the murder of his wife, Sunny, was overturned with the help of Alan Dershowitz. Dershowitz’s book on the case was later turned into the movie Reversal of Fortune, and Jeremy Irons won the lead actor Oscar for his portrayal of von Bulow.
