“Youth” is a beautiful, must see movie starring one of my all time favorite actors: Michael Caine. Caine is an actor of stature who is also a movie star with genuine glamour. In Paolo Sorentino’s masterful film, he plays a retired orchestra conductor who is spending his summer in a luxury spa in beautiful Switzerland alongside his longtime friend and movie director Harvey Keitel. Caine may be retired, but a representative from the Queen of England comes to ask him to perform his most famous composition during a special concert. He refuses, citing personal reasons that we discover later on. And slowly this spellbinder of a movie reveals itself as a meditation on life and youth. Sorentino works his usual magic and his cinematographer Luca Bigazzi makes the most of his stunning location. And Caine, at 83, gives a staggering performance: fearless, unforgettable and in its own way a work of art. You can’t possibly miss that.
