Perfecting your Oscar acceptance speech is almost as tough as winning the gold statuette in the first place. An Academy Award win often marks the highest form of achievement in an actor's career. However, it’s what the recipients say once they win the award that often makes front-page headlines. For decades stars have been using the Oscars stage as a platform to highlight causes important to them or the films they were recognized for. Often stars have also used the big moment to champion political and social causes that are close to them.
