Scherzinger is superb but why’s the set so dark and ugly? Sunset Boulevard, at the Savoy Theatre, reviewed

Sunset Boulevard is a re-telling of the Oedipus story set in the cut-throat world of Hollywood. Pick a side in this tortured yarn. There’s Norma, a burned-out sex-goddess, who wants to make a comeback as a teenage ballerina in a dance epic. Or there’s Joe, a penniless scribbler, who becomes Norma’s reluctant toyboy while he works on her doomed screenplay (which stands for a stillborn child).

Clinging to Joe is Betty, a drippy girlfriend who represents escape and artistic integrity. The final piece in the jigsaw is Norma’s discarded husband, Max, who stands for sadistic and destructive obsession. Each day he sends Norma a new batch of counterfeit love letters from non-existent fans.

Every character behaves either badly or madly. And the success of the narrative rests entirely on Norma’s looks. If she’s elderly, the story is tragic.
