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 (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.
- 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 Despereaux knocks out Ronnie Ives, Gus says to him "it's been emotional", Vinnie Jones who plays Ronnie Ives says this same line at the end of Lock, Stock & Two Smoking Barrels
- With this episode, Timothy Omundson becomes the only regular cast member (beside James Roday and Dulé Hill) to appear in every episode of the show.
- 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.'
