 Annas has an important role in "Jesus Christ Superstar", as one of the two main antagonists of the show (the other being Caiaphas) spurring Pontius Pilate to take action against Jesus.In almost all versions, Annas has a very high voice (almost reaching falsetto) to contrast against Caiaphas' bass.Despite being Caiaphas' father-in-law, Annas is generally played by a younger actor.
