A Grim Foreshadowing
The movie Sunshine is centered around the crew of the spacecraft Icarus II. On their way to the sun, they receive a distress signal for Icarus I, its predecessor that had gone missing before their voyage. In an attempt to rescue whatever stragglers are left, the crew board Icarus I but soon come to realize that there’s absolutely nobody left to save.
As the crew’s flashlights hit the camera lens, there’s a brief moment where astute viewers would’ve seen spliced images of the Icarus I’s crew members. This subliminal message was a way to instill fear and uncertainty in the minds of viewers without them even realizing what was going on.
