Trivia: When Harm is landing the 747, there is a camera shot of Air Force One.

Sins of the Fathers Chapter 9: Tombstone - S3-E9

Unraveling - S1-E7
Trivia: Christina is thrown out of her house after the revelation that she's been lying about her life, and leaves town on a Greyhound as the camera pans down to reveal a sign saying "Now leaving Point Pleasant. Please come back soon.". This is almost identical (both the shot of the sign and the story behind it) to the Buffy The Vampire Slayer episode "Becoming" (2x21) - both the show's executive producer (Marti Noxon) and the writer of this episode (Diego Gutierrez) are former BtVS writers.
Trivia: The working title for "Life on Mars" was "Ford Granada" - a reference to the car that appeared in the 1970s Police Drama "The Sweeney".

Trivia: The episode revolves around a man killing people with the same first names as the thirteen apostles (Mary Magdalene being the 13th), and killing them in a similar fashion in which the apostles died. At one point, Colby and David find a box with a mannequin's head in it. This is a reference to the film Se7en, in which seven people are killed for committing one of the seven deadly sins. The film ends with the main characters finding an actual head in a box.
Curiouser & Curiouser - S2-E22
Trivia: All the sets in the dream sequence, particularly Nick's loft, are filled with props referencing Lewis Carroll's Alice in Wonderland books. They include white rabbits, flamingos, walruses, a squeaky-toy caterpillar - even a half-eaten piece of cake in Nick's fridge. The episode also has several background extras in Wonderland-style costumes, and numerous other references to the books, such as Nick literally falling through the looking glass at the end.
Trivia: As the detectives are trying to find out from Doug Hutchinson's character where the victim is being held, the detectives find out he is somewhat claustrophobic. They decide to scare him and put him in a cupboard without any light. This is very similar to Doug Hutchinson's character in The Green Mile. The main characters decide to punish him and force him into a dark and small room.
Trivia: In "Four dreams" the alternative Allison who doesn't have children looks at some kids in a restaurant and gets a dreamy look on her face. The mother of the children she is admiring addresses her daughter as "Sofia". The "real" Allison's daughter Ariel is played by actress Sofia Vassilieva.
Trivia: Here and in several other episodes, Burke's Law was one of the first TV series to break with longstanding Hollywood prejudices by hiring Latino actors like Cesar Romero to play Latino roles. In this episode, three years before becoming the Joker on Batman, Romero plays a Mexican police chief interrogating Amos Burke, whose rather prescient line to him is, "The joke's on the joker - I've been framed!"
