- Actor Allusion:
"Don't do anything I wouldn't do. (hardly a beat) That doesn't really narrow it down. That's like minigolf, and sushi."
- David Tennant uses the same accent he used during his tenure on Doctor Who (he's actually Scottish). He even draws out his "Well...", which was one of Ten's catch phrases. Peter also holds the stake like Ten does the sonic. There's even a very Ten-like line in the end.
- Dawson Casting: Dave Franco plays a high school student despite being 26 and playing a medical student in the final season of Scrubs.
- Fake American: Anton Yelchin (born Russian, rased in America), Imogen Poots (English), Colin Farrell (Irish), and Toni Colette (Australian).
- Fake Brit: Scottish David Tennant as the English Peter Vincent. See Actor Allusion.
