Blues Brother and Saturday Night Live stalwart John Belushi coined his own wildly popular form of adrenalised, physical comedy performance before his death from a drug overdose in 1982. This feature-length documentary from filmmakers RJ Cutler and John Battse examines Belushi’s unpredictable nature and massive success, both as an original cast member of SNL and later as a bankable movie star, before his drug abuse problems caused his demise. The film also features insightful and rare testimony from Belushi’s widow Judith. Ammar Kalia
