THE AMAZING JOHNATHAN DOCUMENTARY Stream on Hulu. At its finest, magic is a mixture of truth and illusion. John Szeles, better known by his stage name The Amazing Johnathan, walked the fine line between the two during his long performance residency in Las Vegas that began in the 1980s. Then, in 2014, he learned he had a terminal heart condition and only a year to live. It seemed his career was about to be abruptly cut short — or was it? Ben Berman, directing his first documentary, follows the quirky illusionist as he tries a to go on tour. The film provides as much heart as it does mystery in the search for what is really behind Szeles’s story, and weaves a twisted path in which the magician drops one bombshell after another, from serial drug use to a possible revelation about the reality of his diagnosis. Even when it comes to magic, the truth may just be stranger than fiction.
