Review By Greg Klymkiw

"Stars have a life cycle much like animals. They get born, they grow, they go through a definite internal development - and finally they die, to give back the material of which they are made so that new stars may live." - Hans Bethe, "Energy Production in Stars"

Fusion is the future of energy. It is created by slamming two hydrogen nuclei together. When these two positives collide, we get - Voila! - mega energy. Simple, yes? Uh, no. Our sun, and in fact all stars, are essentially fusion reactors. To create energy from fusion, we essentially need to create our own version of the sun.

Sounds like science fiction to you, right? Well, mankind has been actively studying the potential of fusion for over 50 years and now, with the complex participation of 37 countries and the best/brightest scientific minds, this reality is so close, yet so far.

Let There Be Light is a fascinating, gripping study of what might be the most expensive scientific experiment ever undertaken (ITER, the International Thermonuclear Experimental Reactor).

Filmmaker Mila Aung-Thwin with co-director/cinematographer Van Royko serve up everything you always wanted to know about fusion, but were too uninformed to even bother asking about. Using a dazzling blend of animation, digital effects, penetrating interviews and stunningly shot coverage of the complex mechanics and construction of an actual star-making machine deep in the bucolic countryside of France, this is a science-based documentary with a difference.

It's absolutely thrilling, because what we're watching are real scientists racing against the clock to make this important dream a reality. It's a Michael Crichton thriller come to life, only the stakes are much higher. What Let There Be Light serves up is the future of the Earth itself. Stakes don't get much higher than that.

THE FILM CORNER RATING: **** 4-Stars

Let There Be Light, from EyeSteelFilm, enjoys its Canadian Premiere at Hot Docs 2017.
