Mysteries of the Unseen World uses the latest technology to show us things that are too fast to see with the naked eye - what happens to a raindrop when it hits the ground for instance; too slow (plants growing); and just not visible to the human eye at all - like that space dust.
It's a fascinating fim, and I thInk we all learned something from it - two adults and two eight-year-olds. The kids particularly enjoyed the 3D element - on a massive IMAX screen it is far more in your face than your average 3D movie - and I enjoyed finding out about the nano universe and what the future may hold as scientists become able to see the smallest components of life on earth.
It's a shame that there is a US soundtrack (even though it is voiced by actor Forest Whittaker) but it doesn't detract too much - and adults and kids alike gave it a firm 4.5 out of 5.
I do wonder at the pricing though - £30 for a family of four for a film that is less than an hour long. Nonetheless, it's a beautiful film, with amazing visual appeal and some fascinating facts. See the trailer here.
