A story of friendship and film, race and revival, rhythm and blues, centred around Dan Ackroyd and John Belushi and the making of their iconic 1980 film, The Blues Brothers.

The Blues Brothers hit theatres on June 20, 1980. Their scripted mission was to save a local Chicago orphanage; but Aykroyd, who conceived and wrote much of the film, had a greater mission: to honour the then-seemingly forgotten tradition of rhythm and blues, some of whose greatest artists - Aretha Franklin, James Brown, John Lee Hooker, Cab Calloway, Ray Charles - made the film as unforgettable as its wild car chases. Much delayed and vastly over budget, beset by mercurial and oft drugged-out stars, The Blues Brothers opened to outraged reviews. However, in the 44 years since it has been acknowledged a classic: inducted into the National Film Registry for its cultural significance, even declared a 'Catholic classic' by the Church itself, and re-aired thousands of times on television to huge worldwide audiences. It is, undeniably, one of the most significant films of the 20th century.

The saga behind The Blues Brothers, as Daniel de Vise reveals, is epic, encompassing the colourful childhoods of Belushi and Aykroyd; the comedic revolution sparked by Harvard's Lampoon and Chicago's Second City; the birth and anecdote-rich, drug-filled early years of Saturday Night Live, where the Blues Brothers were born as an act amidst turmoil and rivalry; and, of course, the indelible behind-the-scenes narrative of how the film was made, scene by memorable scene. Based on original research and dozens of interviews probing the memories of principals from director John Landis and producer Bob Weiss to Aykroyd himself, The Blues Brothers illuminates an American masterpiece while vividly portraying the creative geniuses behind modern comedy.
