8x01 Lock, Stock, Some Smoking Barrels and Burton Guster's Goblet of Fire
First Aired: Jan. 08, 2014 on USA
Summary: Gus attends a Harry Potter convention in London in the Season 8 opener.
- Goof (errors made by characters, possibly deliberate errors by the filmmakers): At around 23 minutes, Gus (aka "The Wiz") throws exploding powder and calls out "magic" words "Expecto Patronum," but in the Harry Potter books the Expecto Patronum spell doesn't cause any kind of explosion. It scares away an evil ghost like creature called a "Dementor."
- Goof (factual errors): The Interpol agents are shown as being regular policemen capable of making arrests. However, Interpol acts as an information clearing house and liaison between different countries; they do not have authority to arrest anyone.
- The final slow motion fight scene is a nod to the Guy Ritchie movies (Snatch, Lock Stock, etc.)
- Towards the end of the episode, in Despereaux's final scene, he can be seen handling the dagger/key from 'Indiana Shawn and the Temple of the Kinda Crappy, Rusty Old Dagger.'
- When Shawn is wildly guessing names of his doppelgänger's mother during the interview with Interpol's director in the beginning, he uses the names of Glen, Mulva, Rollergirl, and Starchild. Glen is most likely from "Glen or Glenda" (1953). Mulva is probably from Seinfeld, "The Junior Mint" (season 4, episode 19), but given Shawn's penchant for obscure movies, could be from "Mulva: The Zombie Ass Kicker" (2001). Rollergirl is from "Boogie Nights" (1997). Starchild obviously is from "2001: A Space Odyssey" (1968).
- When showing the newspaper coverage in the beginning of the episode, the pictures are moving. A nod to the moving images in the Harry Potter series and the reason Gus wanted to go to England.
- At the end, Gus and Shawn bemoan the fact that they were so busy working on the case that they didn't get to see much of London and that they could have just as easily spent their time in British Columbia. This is an inside joke as that is where the show is filmed.
