BORIS KARLOFF: THE MAN BEHIND THE MONSTER (2021) **** Thomas Hamilton's insightful and illuminating documentary on the legendary horror icon offers a full display of the actor's canon from bit player to Hollywood royalty with rare pictures and talking head tributes from the likes of filmmakers Guillermo Del Toro, John Landis & Joe Dante to fellow thespians such as Ron Perlman and Christopher Plummer. Karloff's English gentleman off-screen persona counterbalanced the often sinister and deeply scary onscreen madmen and monstrosities that he enlivened with his own trademark heart, passion and pathos. As Frankenstein's monster he cemented what would be a unique legacy of the genre as well as his generosity for his fellow man. A must for fans and future filmmakers.
