Maria is a film by Pablo Larrain, who appears to have a soft spot for the psychodramas of legendary women (Spencer, Jackie) and has turned his attention to the prima donna Maria Callas. It stars Angelina Jolie, who trained as an opera singer for the role, God bless her, and while her voice is sometimes blended with Callas’s – isn’t that like adding ordinary plonk to a Château Lafite? – it still feels like karaoke, albeit karaoke of the most elevated kind.
