~	The necklace Cassie wears is a little silver Spitfire fighter plane.
~	The book Cassie keeps reading is Lady Chatterley's Lover.
~	Capa has a dog, and his name is Maxwell.
~	Harvey keeps a collection of love letters between him and his wife in his cabin.
~	The Payload was originally the mass of the moon and made of highly compressed dark matter instead of fissile materials. The moon is massive enough to have its own gravity: 1/6th that of Earth, which explains how Pinbacker was able to pick up Capa so easily. However, the film's science advisor pointed out problems with using a bomb that massive, so it was reduced to the size of Manhattan island. (1)
~	Sunshine's science advisor, Brian Cox, works for the world's largest particle physics laboratory, CERN. He and 5,000 other scientists are currently working on the Large Hadron Collider, the most powerful particle collider ever built. It is perhaps the biggest, most expensive, and most important scientific experiment ever conceived, and when it is switched on in 2008, has the potential to recreate the conditions of the Big Bang!
~	"The plot does not revolve around the sun dying in the normal sense: this is not due for around five billion years based on our understanding of nuclear fusion. It has instead been "infected" with a "Q-ball" - a supersymmetric nucleus, left over from the big bang - that is disrupting the normal matter. This is a theoretical particle that scientists at CERN are currently trying to confirm, and was one of the many contributions of the science advisor. The film's bomb is meant to blast the Q-ball to its constituent parts which will then naturally decay, allowing the sun to return to normal." (1)
~	"[Alex Garland] wrote Sunshine as a film about atheism. A crew is en route to a God-like entity: the Sun. ... As the crew travel nearer to the Sun, the majesty of the burning star fries their minds. ... Ultimately, even the most rational crew member is overwhelmed by his sense of wonder and ... believes he is touching the face of God. But he isn't. The Sun is God-like, but not God. ... The director, Danny Boyle, ... felt differently. He believed that the crew actually were meeting God. ... The two interpretations ... were the same two interpretations that could be made from the world around us." (2)
