- Actor Allusion: Sheriff Corbin, played by Clancy Brown, is killed by decapitation. Brown famously played the immortal Kurgan in Highlander, who could only be killed by beheading.
- Fake Brit: Both for real (see Fake Nationality below) and in-universe, when Ichabod mistakes a woman for Katrina and she speaks to him with an English accent - until he corrects a mistake she made, whereupon she switches to her regular American voice and tells him he's at a historical recreation.
- Fake Nationality: Katia Winter is from Sweden. Also, Jenny Mills and Ichabod's father are played by Canadians (Lyndie Greenwood and Victor Garber).
- Fan Community Nickname: Sleepy Heads.
- Name's the Same: Abbie Mills is also the name of the female lead in Harper's Island. Aside sharing a name and having a father-figure in their local sheriffs who are later killed by their respective series' villains, they don't seem to have much in common.
- Playing Against Type:
- You Look Familiar:
- Months before the Bones/Sleepy Hollow - crossover episode, Jessica Camacho, who plays Jenny's rival Sophia Foster, was guest starring on Bones (as another character).
- There's also an actor who played a character on this series and then ended up playing another character on Bones who shared the same last name.
