At the end of the credits the sound of the distress beacon of the Icarus can be heard in the background.
The Fox Searchlight logo runs backwards at the beginning of the film, then zooms into the setting sun, which then turns out to be the Icarus II.
Scenes from the film in chronological order are played during the end credits in a small box on the left side of the screen, which moves from the top to the bottom as the credits roll.
The opening words of the film's title SUNSHINE seem to burn up from the heat of the sun.
