Bellow is the opening monologue from Sunshine. You may have qualms about the third act, but if you like a good hard scifi movie check out SUNSHINE. Danny Boyle works in great colors and heat.
"Our sun is dying. Mankind faces extinction. Seven years ago, the Icarus project sent a mission to restart the sun, but that mission was lost before it reached the star. Sixteen months ago, I, Robert Capa, and a crew of seven, left Earth frozen in a solar winter. Our payload: a stellar bomb with a mass equivalent to Manhattan Island. Our purpose: to create a star within a star. Eight astronauts strapped to the back of a bomb. My bomb. Welcome to the Icarus Two."
