Directed by Danny Boyle in 2007. Written by Alex Garland (28 Days Later...).
Very cool movie. Boyle/Garland did an excellent job of kick starting the sci-fi genre, at least IMO, even if it was only for a little bit.
I just finished playing Dead Space (video game) too, and Sunshine reminded me of it... so I was really into it.
Check it out. Sunshine (and Rose Byrne ) gets Bill the Butcher's Official Stamp of Approval.
