In the Marvel comic books, Colleen Wing is the best friend and crime fighting partner of Misty Knight. Knight, portrayed by Simone Missick, is a main character in this show, "The Defenders (2017)," and "Luke Cage (2016)."

In the comics, Ward Meachum (Tom Pelphrey) is the uncle of Joy Meachum (Jessica Stroup), but in the series they are brother and sister.

The "Iron Fist" comic book series was originally inspired by the success of the "Kung Fu (1972)" television series. The hidden land of K'un L'un was inspired by various stories, including James Hilton's "Lost Horizon" and tales of Tibet. Much of the original series was inspired by the Golden Age Centaur Comics character Amazing Man, who was a westerner who gained super abilities while studying in a hidden Tibet-like land. Amazing Man, as his civilian identity of John Aman, was added to "Iron Fist" continuity in the "Immortal Iron Fist" series.

Rosario Dawson is the only actress to appear in four of the Marvel Cinematic Universe shows on Netflix: Daredevil (2015), Jessica Jones (2015), Luke Cage (2016), and Iron Fist (2017) (as well as the crossover series, The Defenders (2017)).

Despite the criticism of Danny Rand being played by a Caucasian actor, the Danny Rand in the comics was indeed Caucasian with blond hair and green eyes. Even so, the "Iron Fist" comics were inspired by Kung Fu (1972), wherein a white actor played a half-Chinese character.

The character of Iron Fist was introduced in 1974 in Marvel Premiere #15 by Roy Thomas and Gil Kane. This was around the same time the Kung Fu movie genre was rising due to the popularity of Bruce Lee (who passed away a year earlier). Iron Fist's philosophy parallels Lee's in that one must focus his/her mind (Lee famously said, "Empty your mind and be like water.") in order to control your body and power. An example of this is Bruce Lee's famous "One-Inch Punch" where he could generate explosive power from a punch traveling a short distance. Iron Fist performs a similar feat when he harnesses his Chi to also generate explosive power to get through tough obstacles.

Throughout the series, Claire Temple (Rosario Dawson) says "Sweet Christmas", which is Luke Cage's catchphrase.

Big Al's philosophy about farming being "The Worst Mistake in the History of the Human Race" is not the ranting of the deranged mind of a homeless man. It actually comes from a 1987 paper of the same name by noted American scientist Jared Diamond, and makes the case that modern ills such as pandemics, war, sexism, and social stratification, among other things, can all be traced back to humanity's adoption of agriculture.

According to the review aggregator Rotten Tomatoes, this series received the largest second season increase of reviews since the site started recording television reviews, with a 31% increase.

The Iron Fist previous to Danny Rand was Orson Randall, a combat veteran of World War I that used "gun fu" (as opposed to Kung fu).

Episode 6, "Immortal Emerges From Cave," was directed by RZA. RZA is a member of the hip-hop group Wu-Tang Clan and created many of their signature beats, which include samples from several legendary kung fu movies. RZA also wrote, directed and starred in the feature film The Man with the Iron Fists (2012). Coincidentally, Dave Bautista was also featured in that movie and would go on to star as Drax in Guardians of the Galaxy (2014) and its sequel, which is part of the Marvel Cinematic Universe that now includes the character Iron Fist.

Series showrunner Scott Buck admitted that he was "rather reluctant" to join the series and that what first began to warm him up to the idea of working on the project was seeing just how great and successful "Daredevil (2015)" ended up being.

The character Scythe played by David Sakurai is actually the first real super villain Iron Fist ever faced in the comics, from his second appearance in Marvel Premiere.

In Season 1, Episode 9, as Danny is walking away from a conversation with Joy, you can clearly hear a man shouting, "Hey! I'm walkin' here!" This line was famously ad-libbed by Dustin Hoffman in "Midnight Cowboy (1969)," as he was nearly hit by a car passing during filming.

Additionally, Dhawan also played Doctor Who's first director, Warris Hussein in the 2013 docudrama An Adventure in Space and Time.
