Sunshine - DVD

Fifty years in the future, our Sun is beginning to burn out, threatening the very existence of life on Earth. That's why the Icarus 2 spacecraft, with a crew of eight and a huge nuclear payload, is heading to our star to try to reignite the Sun.
But in close proximity to the Sun, the crew picks up a distress signal from Icarus 1, which disappeared without a trace six years ago while trying to complete the same mission.
