- Awesome Music: Has its own page.
- Complete Monster: Arthur Savage is, initially, just the strict headmaster of Little Haven's high school, and a consummate Control Freak who lets a glimpse of his true nature show when, during the Zombie Apocalypse, he callously "prioritizes" over an old woman with a heart condition. When Savage's desperate attempts to maintain authority over the survivors fails, Savage decides to allow the zombies in to slaughter all the survivors out of spite, gleefully locking his own students inside while promising to deliver whatever's left of Anna to her father whom Savage looks down upon, even attempting to murder both Anna and her father when they save his life from the ravenous zombies. Savage gleefully hopscotches over the line to demonstrate himself worse than any of the mindless zombies ravaging Little Haven, attesting during "Give Them A Show" that he "might as well have some fun" with the collapse of society.
- Crossing the Line Twice: Anna decapitating a zombie? Horrifying. John's high-pitched scream in response? Hilarious.
- The sight of John as a zombie? Horrible. His novelty sweater lighting up one more time before the scene changes? Guiltily hilarious.
- Ear Worm: Hollywood Ending will get stuck in your head with a vengeance.
- Idiot Ball: Arguably, most of the character deaths are caused by Anna, Steph and Nicks' actions and choices examples include Nicks idea to go through the Christmas Tree Emporium results in not only his friends dying but also John, Lisa and chris die due to Steph not being cautious enough, Annas dad dies due to a combination of her dad and her not realising she had a longer reaching weapon in her hands to stop Savage, also she should of knocked him the hell out with it when reaching the stage in the first place.
- Jerkass Woobie: Nick is a bit of a prick, but over the course of the movie he loses his friends and has to kill his dad, so its easy to feel sorry for him.
- Moral Event Horizon: Savage crosses this line when he lets zombies into the school to devour the survivors inside, just to keep his control over the school.
- Retroactive Recognition: Thoros of Myr left the Seven Kingdoms to become the headmaster at Anna's school.
- Signature Song: "Hollywood Ending" is arguably the most popular song on the soundtrack.
- Spiritual Adaptation: A horror-comedy filled with Made of Plasticine zombies getting killed in Bloody Hilarious ways with ridiculous novelty weapons, Headmaster Savage losing his mind and turning into a textbook psychopath... this is pretty much Dead Rising: The Musical. It even shares the fourth game's Christmas setting!
- Spiritual Successor: To Shaun of the Dead. But a musical!
- Suspiciously Similar Song: "Christmas Means Nothing Without You" sounds more than a little like Mariah Carey's ubiquitous "All I Want For Christmas Is You".
- Theiss Titillation Theory: The dress Lisa wears for her performance looks dangerously close to suffering a Wardrobe Malfunction.
YMMV / Anna and the Apocalypse
