- Accidentally Accurate: The scene in episode 2 where Haruko mentions Misuzu thinking that dinosaurs came from chicken eggs. Misuzu's right, you know. Feathers, air sacs, four-chambered hearts, gizzards, gastroliths, toothed beaks in some birds, pubis bone moved backward into the bird-hipped configuration among some theropods, insulating wings—there's no two-ways about it: Birds are living dinosaurs.
- Cowboy Bebop at His Computer: DVD advertisements describe Kanon as "a prequel to AIR, featuring the same characters". No, and no, despite the Continuity Cameo above. Speaking of the ads, Hurai Suzumiya, anyone?
- And then there's Anime News Network's official review, which messes up the character names.
- Hey, It's That Voice!: Misuzu is played by Monica Rial, who uses a similar-sounding, but more solemn, voice for Lumiere, and very much avoids typecasting as Super Soldier Jo in Burst Angel and vampire-like ninja Okoi in Basilisk. She's been in lots of stuff.
- The other leads in the dub have been in their fair share of anime — Vic Mignogna as Yukito, and Luci Christian as Haruko.
- A case of this in the original made it into an Actor Allusion in Lucky Star (Daisuke Ono and Hiromi Konno, who played the roles of Yukito and Potato, respectively). There's also one in Haruhi Suzumiya (with Daisuke Ono, again).
- Heck, Yukito is Heero Yuy in the game version!
- In the Japanese version Haruko is Skuld, Hijiri is played by Urd and Uraha is played by Belldandy.
- The Other Darrin: The game and movie has Hikaru Midorikawa as Yukito's seiyuu, while the series uses Daisuke Ono.
