A fascinating Broadway revival of the bombastic 1994 musical blows it up even further.Despite Norma Desmond, who famously declares in the film “Sunset Boulevard” that it’s not her but “the pictures that got small,” the opposite is true on Broadway these days. In musicals especially, video and projections have grown ever more dominant. Perhaps it is not so much an irony as an inevitability, then, that at the St. James Theater, where a revival of the musical based on “Sunset Boulevard” opened on Sunday, the pictures — live video streamed onto an LCD screen more than 23 feet tall — are so big they almost blot out the show below.But alas, only almost.For despite many fascinating interventions by the director Jamie Lloyd and his technical team, and the fact that it is based on one of the greatest of movies, the musical remains too silly for words. In that sense, and others, Norma would have loved it.Which isn’t praise. You will recall that Norma (Nicole Scherzinger of the Pussycat Dolls) is deluded: a washed-up silent film star who, in her 50-ish dotage, haunts a grand, ghostly Los Angeles mansion with only her grim manservant and a recently dead chimpanzee for company. By 1949, when the musical starts, she has barely left the premises for decades, let alone made a movie; still, she believes that she, and the silents, could achieve a marvelous comeback if only Cecil B. DeMille would direct her in the epic version of “Salome” she has written.The rest is madness. She conscripts Joe Gillis, a hunky, seedy, unsuccessful screenwriter, to polish her draft and, soon enough, other things. Joe (Tom Francis) seesaws between his luxurious life as Norma’s kept man and the more idealistic promptings of Betty Schaefer, an ambitious studio underling he at first brushes off as “one of the message kids.” Still, when Betty (Grace Hodgett Young) urges Joe to adapt a story of his called “Dark Windows,” they fall in love, while the servant, Max von Mayerling (David Thaxton), offers a dark window of his own into Norma’s modus operandi with men. (Razor and gun included.) None of this ends well, or rather it does not begin well, as the tale is narrated postmortem by Joe’s corpse.The 1950 film, directed by Billy Wilder, stands at a wry remove from these tawdry proceedings, with a cool appreciation but no embrace for human pathos and the hysteria of Hollywood dreams. Norma is a drama queen, Joe a gigolo, Betty a simp and Max a goblin. We know nothing of their emotions beyond what their actions show us.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
