Genius Bonus: There are some obscure references to Holmes trivia. For example, when Holmes first meets John Watson, he guesses that his first name is James. In "The Man with the Twisted Lip", one of the original Sherlock Holmes stories, Watson's wife addresses him as "James", causing rampant speculation from the fans about whether this was a significant slip or just a sign that Doyle had forgotten his own character's name. The in-universe explanation is that James is the most common male name beginning with J.
Narm: The faces that Rathe's sister and Dragon makes when she dies via accidentally ingesting a poisoned dart are so ridiculous that they turn her death scene into this.
"Seinfeld" Is Unfunny: With CGI being so ubiquitous now, it's hard to appreciate just how mind blowing that stained glass knight was at the time.
Suspiciously Similar Song: The cultists performing a human sacrifice chant a song which rips off "O Fortuna" from Carmen Burana.
Viewers are British: The Sdrawkcab Name clue of "Eh tar" being backwards for "Rathe" is a lot harder to spot if you speak a rhotic accent than a non-rhotic one, since with the former you're unlikely to recognize the implied "r" at the end of "Eh tar" in pronunciation (pronounced "etah" in the movie) in the first place.
Visual Effects of Awesome: The Stained Glass Knight. This was the first time CGI was combined with live-action and is still pretty convincing to this day. It was also nominated for Best Visual Effect at the Oscars, but was beaten byCocoon. Bonus points for it being made by Pixar.
