We all know that JJ Abrams is an international man of mystery, a director who has made a career of keeping secrets. What you didn’t know is that he can be a very funny, almost manic person too – qualities which he displays here. From discussing The Graduate to performing magic tricks to examining the fascinations of Lost, he dissects the importance of keeping mum. The talk also works as a tribute to his grandfather, a formative character in his life and a man he commemorates in his movies (his name was Harry Kelvin, hence the USS Kelvin in Star Trek). Recorded in 2007, it’s also interesting in hindsight to note the tributes he pays to Spielberg, his Super 8 collaborator. And as if all that weren’t enough, it contains the line, “Ten years ago to get that shot we’d have had to kill a stuntman.”
