He managed the Bee Gees and created Saturday Night Fever but the closeted impressario ‘never felt that sense of success’ according to a new documentary

According to film director John Maggio, two types of executives run the entertainment industry – one far rarer than the other. “The vast majority of them don’t know what’s good, or what will be a hit, until ten other people tell them,” he said. “But a few can tell you right away. They’re the visionaries.”

For an extended time, one of the most clairvoyant was Robert Stigwood. Yet no one had made a feature documentary about him until now. Mr Saturday Night lays out the rocket-like trajectory of this manager turned producer turned impresario who scored hits in the worlds of music, theater, concerts and film. Stigwood’s projects ranged from managing the Bee Gees to running a record label featuring artists like Eric Clapton to producing two of the biggest movies of all time – Saturday Night Fever and Grease, as well as the successful movie version of the Who’s Tommy – to bankrolling smash plays like Jesus Christ Superstar and Evita. “For a time, he was the Wizard of Oz of entertainment,” said Maggio, who directed the film, to the Guardian. “Between 1970 and 1978, he could not not make a hit.”
