Terry Gilliam turns to eye-watering excess for his staging of Berlioz’s Benvenuto Cellini

Operas about artists are not rare. However — perhaps for obvious reasons — those artists tend to be musicians, singers, or at least performers, able to persuade and cajole both us in the audience and the other characters on stage through their eloquence. Berlioz, in his first opera, presents the renaissance sculptor Benvenuto Cellini, in an episode loosely adapted from his autobiography.
