Richard Hammond takes on the ultimate engineering project. How on earth do you make a planet, or a solar system, a galaxy or even... a universe? To find out, he opens up his cosmic toolbox and builds each one piece by piece, from the top of an impossibly high tower. What does he need to construct the cosmos, and what happens if he gets it wrong? With eye-popping computer graphics, Richard discovers that it takes an entire universe to make our planet just right for us.
From director Todd Douglas Miller comes a cinematic event fifty years in the making. Crafted from a newly discovered trove of 65mm footage, and more than 11,000 hours of uncatalogued audio recordings, Apollo 11 takes us straight to the heart of NASA’s most celebrated mission—the one that first put men on the moon, and forever made Neil Armstrong and Buzz Aldrin into household names. Immersed in the perspectives of the astronauts, the team in Mission Control, and the millions of spectators on the ground, we vividly experience those momentous days and hours in 1969 when humankind took a giant leap into the future.
