* Chuck is horrified when he finds the waterlogged corpse of one of the pilots. Quickly turns into a {{Tearjerker}} when he searches the body and finds a photo of his family, and then a [[SugarWiki/HeartwarmingMoments heartwarmer]] when Chuck gives him a proper burial and grave.

* The very premise can be quite terrifying -- after a devastating accident, you find yourself at the shores of an island isolated from the rest of the world. There are no means of outside interference or communication, no one else on the island to help you survive, and no knowledge of your surroundings. You are back to how man used to thrive millennia ago -- scavenging for food or any type of resource, relying on pure survival instinct ill-equipped if at all, and [[EverythingTryingToKillYou Mother Nature at its rawest from every corner — from severe weather, rocky cliffs, brutal oceans, plant life lethal to the touch, predatory mammals and beyond]]. And the island is still a comparatively easy place to survive - if Chuck had been marooned in a desert, or a mountain, or even just a smaller island that couldn't support much life, such as in Stephen King's ''Survivor Type'', he'd almost certainly have died of dehydration and starvation.

** While building the raft, Chuck needs more vines to use as ropes, and knows where there's some left, but is very reluctant to go get it - because he left it hanging from the tree on top of the mountain as a ''noose'', as part of a suicide attempt he never went through with.

* As does the scene where he knocks out his rotten tooth without receiving proper care from doctors and medicine to help him.

* Chuck's SanitySlippage is another terrifying example. While he remains an intelligent and thoughtful man, [[GoMadFromTheIsolation it becomes clear that the isolation of being stranded has driven him to act more animalistic than before,]] and his originally charismatic and firm personality becomes sullen and quiet in order to conserve energy. His emotional reliance on [[CompanionCube Wilson]] becomes a good example of this, as the grief he feels when Wilson "dies" is clearly very real. It's devastating to realize that Chuck's determination to get back home is the ''only'' thing stopping him from putting himself out of his misery. And when he ''does'' finally get back, his life is completely upended and his fiancé is with another man, and it's clear that Chuck feels out of place after being alone for so long.

* The first time Chuck attempts to leave the island and gets slammed down by a wave, he falls on an underwater coral reef, puncturing his leg. His underwater scream sells just how painful it is. Becomes FridgeHorror when you think about how such a massive wound might get infected (which it does).
** What makes this scene worse is that Tom Hanks really did injure his leg filming that scene.
