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: Michael Mann was originally against casting Don Johnson. Prior to this TV series, Johnson had starred in four failed TV pilots.
Trivia: Sam mentioned an old case from 1999. In the German dubbed version, it's from 1990 (even in the German subtitles it's 1999). Obviously the missing nine years takes to long to fit into the mouth movements. (00:11:10)
Trivia: Former adviser to President Ronald Reagan, Lt. Col. Oliver North, served as a consultant for several episodes.
Trivia: At approximately 29 minutes in, Ernie Hudson says "Who ya gonna call?" He is one of the original Ghostbusters from the 1984 film and this was the popular tag line in that movie.
Trivia: This series was roughly halfway through filming when Marvel suddenly scrapped it and decided to start over, including hiring a showrunner (a first for a Marvel Disney+ series). Reportedly, the original writing had a very legal procedural format, and Matt Murdock didn't even suit up as Daredevil until the fourth episode. In the process of revamping the series, Marvel decided to officially make the original Netflix show canon to the Marvel Cinematic Universe.
Trivia: Michaela McManus (born in 1983) is only eleven years older than Emma Dumont (born in 1994), who plays her daughter.

The Disappearance of Mr. Davenheim - S2-E5
Trivia: David Suchet performed all the various conjuring tricks Poirot is trying to pull off. The illusionist in the theater show at the beginning is the late Patrick Page, real life stage magician and coach/consultant for the episode.
Trivia: Only mentioned in one episode early in the series, Steve Austin's least-referenced superhuman power was his ability to hold his breath for extraordinary lengths of time. Steve's phenomenal breath-holding ability was due to the fact that, even though he had two normal lungs, he had a much smaller circulatory system than a normal human being. Also, the Steve Austin in Martin Caidin's original book, "Cyborg," had an entire array of weapons, flares, communications gear, retractable swim fins, and scuba tanks built into his bionic body.
Trivia: Although Laurel is a couple of years older than Sara, Katie Cassidy is only about a month older than Caity Lotz.
Trivia: Although many realistic freeway numbers and exits mentioned over the 2-way radio are real, they were not used in the show. An unused section of the 210 freeway (close to the 118 freeway) in the San Fernando Valley that wasn't quite open to the public yet, was the location nearly always shown on the show representing whatever location is mentioned. If you see many episodes, you can see the same section of freeway always shown.
Trivia: Originally, the new "Ghost Face" mask was meant to be made out of human flesh that was being stretched over the killer's face, hence it distorts and resembles a "screaming face" like the original Ghost Face mask. This idea was dropped relatively early in filming. However, several scenes had already been filmed with the killer for the pilot, so in some shots, the mask is actually a CG model that's been added in over the original. (Though thankfully it's hard to tell which scenes have the digital mask).
Trivia: The news on the cell phone seen by Danny is written by Keira Morrisette - she is a co producer of the show.
Trivia: Elsbeth suspects that a "suicide" is actually a murder because the victim had recently used teeth whitening strips. This is similar to the last Columbo episode, "Columbo Likes the Nightlife", where the "suicide" victim has recently used mouthwash and trimmed his toenails. In each case they didn't believe a person would do those things right before taking his or her own life. Elsbeth also often turns around with "just one more thing" after walking away, just as Columbo often did.
Trivia: The name on Jenkins' disguise is "Chuck Spadina." When Keanu Reeves first came to Hollywood, he was told his name was "a little too exotic," and it was suggested he should change his name. Chuck Spadina was one option he considered, although apparently not very seriously.
Trivia: The lakeside cabin Jane bought was shot on location at Disney's Golden Oak Ranch. It is called 'Cabin by the Lake'. Http://www.lamag.com/citythinkblog/scene-golden-oak-ranch-mentalist/.
