- Actor Allusion:
- Red John's last appearance, where he talks down to Jane and tries to kill him, only for Jane to gain the upper hand and kill him as he resorts to pleading to live. Sounds a lot like Percy's death, especially since Xander Berkeley played both characters.
- When Sean Maher shows up as an antagonist to Jayne - ahem, Jane - he says the speech that the Victim of the Week was going to give was about River rafting...
- Also, since Lisbon (Robin Tunney) is best known for being Sarah in The Craft, the whole episode "Red Rum" had a bit of this. And Lisbon's crazy looked remarkably Tourette's-ish, Tunney's other major role being the lead in Niagara, Niagara.
- Jane commenting "You should have seen me ten years ago" might be a Shout-Out to Simon Baker's 2001 drama series, The Guardian.
- California Doubling:
- Although the show takes place (almost) entirely in California (occasionally having ventured into neighboring areas like Tijuana or Vegas), it is mostly filmed in Los Angeles (despite being based in Sacramento and most episodes taking place in NorCal as opposed to SoCal).
- The opening scene of "Days of Wine and Roses" really takes the cake—it's said to take place in the Tenderloin in San Francisco, but the Tenderloin is considerably more built-up and dirty than the area depicted. There are only a small handful of parks in the area, and none seem like a suitable place to sit and play chess.
- The Visualize cult compound in "Red All Over" and "His Thoughts Were Red Thoughts" is The House of the Book performance hall and library building at the American Jewish University, Brandeis-Bardin Campus in Simi Valley, California.
- When the show moved to Austin, there was quite a bit of this.
- Directed by Cast Member: When Simon Baker directs episodes, prepare for your darkest episodes ever, both in lighting and storyline.
- Fake American: Jane is played by Simon Baker, an Australian, while Rigsby is played by Owain Yeoman from Wales. They both pull off impressively solid American accents, though Baker's native New South Wales accent can be heard near the end of most episodes as he says "Stay tyooned fer scenes from ow' next eppasode."
- Fake Nationality: Lisbon is of Portuguese descent according to Bruno Heller. Her actress Robin Tunney is Irish-American.
- The Other Darrin: One of the biggest challenges for fans trying to figure out who he is, is the fact that Red John made appearances before the actor who plays him was cast. Like Sylar on Heroes, they were played by various stunt doubles and extras. As a result some of his earliest appearances, like in "His Red Right Hand", he doesn't resemble any of the final suspects. In "Red John's Friends", Red John IM's Lisbon's team. The person typing in real life was Simon Baker, leading many to believe that Patrick Jane was Red John.
- Real-Life Relative: Simon Baker's, Tim Kang's and Owain Yeoman's wives have all appeared on the show.
- Recycled Script: A plot from 2014 where Theresa goes undercover in prison in order to become friends with a female carjacker so they can catch her boyfriend was used in an episode of Dark Justice in 1993.
- Screwed by the Network: Fans have been accusing CBS of this since Season 5. First they put the series in a graveyard shift (10 PM Sunday), then every so often they force it to compete with football and other highly-rated shows. At the same time, the series itself has seen its share of critics increasing since Season 4, who accuse the writers of pulling The Chris Carter Effect with its Red John Myth Arc. In the middle of the final season, they moved it to a new timeslot on Wednesday nights with little advance notice. They also started it in the middle of the television season with a limited episode order and the announcement that this was the final season.
