The best Julian Rhind-Tutt’s documentary movies

Over 100 years ago, Albert Einstein grappled with the implications of his revolutionary special theory of relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2. In "Einstein's Big Idea," NOVA dramatizes the remarkable story behind this equation. E = mc2 was just one of several extraordinary breakthroughs that Einstein made in 1905, including the completion of his special theory of relativity, his identification of proof that atoms exist, and his explanation of the nature of light, which would win him the Nobel Prize in Physics. Among Einstein's ideas, E = mc2 is by far the most famous. Yet how many people know what it really means? In a thought-provoking and engrossing docudrama, NOVA illuminates this deceptively simple formula by unraveling the story of how it came to be.

A true pioneer in audio exploration and psycho-acoustics, Delia Derbyshire conceived one of the most familiar compositions in science fiction, the Doctor Who theme, while working in a BBC basement. Her soundscapes felt like they connected to another realm. Kicking off with the discovery of 267 tapes in an attic, along with a treasure trove of journals hidden in her childhood bedroom, this film tunes in to Derbyshire’s frequency; that of a life-long non-conformist, whose peals of laughter in an archive interview tickle with delight and eccentricity. Featuring a rich archive, interviews, fictional embodiment and Cosey Fanni Tutti’s psycho-sonic channelling, director Caroline Catz traces acoustic pathways on her archeological dig into Derbyshire’s resonant life.

Michael Palin, Clive Dunn and Ian Lavender are among those who contribute to this candid portrait of actor John Le Mesurier.
