- He is the only character in the Shrek series (besides Quasimodo) to originate from a horror story; he's also the only non-fairy tale based character to appear thus far.
- While all of the villains in Shrek the Third had established rivals that motivates them to reign terror, the Horseman didn't have anyone who particularly made him drown in sorrow. At the very least his backstory wasn't mentioned by Charming during his speech.
- His reasons for drinking in the Poison Apple might have to do with his inability to properly chop heads off, opting to throw flaming pumpkins instead as seen in The Legend of Sleepy Hollow.
- Despite being a recurring character, he never appeared in the video games.
- In the Shrek comics, he has a different outfit-- it's more faithful to his descriptions in The Legend of Sleepy Hollow, as he's wearing a uniform worn by soldiers during the American Revolution.
- The outfits in the movies however vaguely resemble the outfit worn by the version seen in Tim Burton's Sleepy Hollow.
