* SugarWiki/FunnyMoments: “No, Marcus, I do not want to spend Christmas with Miss Granola Suicide and her spawn.”
* GeniusBonus: There is a scene where Marcus thinks he sees his mother across a crowded park, but when he finally gets to where he saw her she isn't there. This scene is never referenced again, but it takes place at the exact moment that Marcus's mother [[spoiler:attempts suicide. There are many reported cases where someone sees someone they know in an unexpected place, but then they disappear, only to later find out that the person died at the moment, or was in a life-or-death situation. It's often called a "crisis manifestation".]]
* HilariousInHindsight:
** Creator/NicholasHoult playing an awkward, odd looking kid who gets bullied as a result, [[http://31.media.tumblr.com/e0cefab9fb228b5201fed079d1fbb3bc/tumblr_mqrbpsVW3h1sckm4yo1_1280.jpg when here's how he looks nowadays.]]
** Will starts complaining about Christmas songs being played [[ChristmasCreep mid November]], but within the next decade that would become very late for hearing the first Christmas song.
* HollywoodHomely: WordOfGod is that Nicholas Hoult was a little too good looking to be believable as a social outcast, so they gave him an unflattering bowl haircut.
* RetroactiveRecognition:
** Suzie is played by Victoria Smurfitt, who'd later become known for playing none other than [[WesternAnimation/OneHundredAndOneDalmatians Cruella DeVille]] in ''Series/OnceUponATime''.
** Ellie is played by Creator/NataliaTena, aka [[Film/HarryPotter Tonks]] or [[Series/GameOfThrones Osha]].
* TheWoobie: Marcus one-hundred percent. When a character's first line is "There are some people who had a good time in life. I was starting to realize I wasn't one of them", you can tell it's not going to be a happy film for them. Fiona also counts due to her struggles with depression.
