Trivia: Bradley Walsh had never seen the original American series before being offered his role.

Trivia: Actor Balthazar Getty is the son of the subject of this series, John Paul Getty III.

Trivia: While it's not explicitly stated, the Superman from another earth played by Brandon Routh is the one from Superman Returns (and by extension that from the original Superman movies). Aside from the obvious factor of the same actor, he name checks his son Jason, which is what his son with Lois was called in that movie too. His reference to fighting himself relates to Superman 3.

Trivia: This show pays many homages to the 1968 film Bullitt which was also set in San Francisco. Firstly officer Rebecca Madsen's car is the exact same make, colour, and model Mustang that Steve McQueen drove in Bullitt. Also the final episode (Tommy Madsen) features a car chase which recreates many shots from the 1968 film. It even includes the green Beetle Volkswagen coming down the hill as seen in the movie.

Trivia: A number of the actors portraying police officers, suspects, and others have a southern accent, even though the show is set in Colorado. That is due to the fact that, although establishing shots were filmed in Colorado Springs, the reenactments were filmed in Tennessee, to save on costs.

The Hustlers News of the Day - S3-E5
Trivia: In some versions of this episode the name of the newspaper the grifters con has been rather clumsily dubbed over as "The Weekend World" rather than the original "The Sunday World", which is a real newspaper.

Trivia: John Munch is the only fictional character played by a single actor to appear on eight different TV series. He was a series regular on Homicide, and crossed over onto "Law & Order", "The X-Files", "The Beat", "Law & Order: Trial By Jury", "Arrested Development", "The Wire", and became a series regular on "Law & Order: Special Victims Unit".

Trivia: Andy Griffith was the only actor to appear in all 195 episodes of the series.

Flight Risk - S2-E4
Trivia: In this episode, Dan Cooper hijacks and robs the passengers, then jumps out of the plane mid-flight with over $1 million of goods. In 1971, a man identifying himself as "Dan Cooper" (later misidentified by the media as "D.B. Cooper", which ended up being the more popularised epithet) hijacked a plane and jumped out of the plane in mid-flight with over $200K (equivalent to over $1 million in 2017).

Trivia: Instead of the Royal Air Force, the series has a fictitious British Air Force with largely invented insignia. Ranks are taken from the RAF, but sometimes different rank insignia is worn (e.g. an air vice-marshal wearing air marshal's insignia and a flight lieutenant wearing flying officer's insignia, although another flight lieutenant wears correct insignia).

Trivia: In this episode, the murder victim's name is given as Reiko Hashimoto, and at one point, Gannon shows Friday a couple of photographs of her. Reiko Hashimoto was the maiden name of Reiko Douglas, the wife of comedy writer, author, and perennial talk show guest Jack Douglas, and the photographs used are of her.

Trivia: Anthony Andrews was the first choice for the role of Remington Steele, but he turned it down.

Trivia: Lieutenant Decker is the same Decker from The A-Team TV show.

The Trial of Audrey Parker - S1-E11
Trivia: When Audrey is looking for a secret compartment in the bookcase, you can see a copy of "The Tommyknockers." This is a Stephen King novel that's set in the town of Haven.

Trivia: In an homage to the king of Hawaii-based cop shows, Hawaii Five-O, Don Ho tells MacBride and Ryan at the end that if they ever break up his night club again, he's going to call McGarrett. Ryan gives MacBride a baffled look and just before the freeze-frame, queries, "Who's McGarrett?"

Trivia: This is the first Power Rangers season that wasn't dubbed in Japanese.

Trivia: Aside from his considerable talent and theatrical qualifications, the reason that Jeremy Brett's portrayal of Sherlock Holmes was so nuanced, meticulous and authentic is because the role was therapeutic to him. In real life, all throughout the various Granada Television series (from 1984 to 1994), Brett was plagued with manic-depression, erratic behavior and heart problems, from which he fatalistically felt he would never recover. Immersing himself in the mentally-disciplined character of Sherlock Holmes gave Brett much-needed focus and clarity in the last ten years of his life.
