- Creator Breakdown: Scott Stapp had a long and tremulous one. At one point, the band was sued by concertgoers as Stapp was reportedly "so intoxicated/medicated that he was unable to sing the lyrics to a single Creed song." Eventually led to the souring of his relationship with the rest of the band, and Creed's (temporary) breakup in 2004. Between this and their reunion, he attempted suicide at least once, and even post-reunion, he went bankrupt, lived for several weeks in a hotel and progressively went more and more insane, eventually culminating in a vicious anti-Obama rant, then driving all around Florida in a drunken stupor selling off priceless possessions to strangers. As it turned out, he's bipolar and hadn't ever been diagnosed until his meltdown.
- Actor-Shared Background:
- One of Rocky's main issues is about his son moving to Vancouver in order to escape his famous father's shadow. In real life, Stallone's oldest son Sage died of a heart attack while Creed was in pre-production, which influenced his and Coogler's decision to focus more on Rocky's father-son relationship with Donny.
- In a more minor case, Ricky Conlan and his actor Tony Bellew both hail from the rough part of Liverpool and are fans of the football team Everton FC. Both Conlan and Bellew also have two kids.
- Approval of God: Carl Weathers, who played Apollo Creed, gave his strong endorsement to the movie and Michael B. Jordans performance. Jordan felt extremely honored.
- Career Resurrection: Not exactly, but Michael B. Jordan was lucky that this film came out so soon after Fantastic Four (2015) and thus preemptively repaired the damage that film could have done to his career.
- Cast the Expert:
- 'Pretty' Ricky Conlon is played by real life Liverpool boxer 'Tony 'The Bomber' Bellew'.
- Danny 'Stuntman' Wheeler is played by Oakland's Andre 'S.O.G.' Ward, one of the top pound for pound boxers in the world over the last 8 years. Additionally, Leo 'The Lion' Sporini is played by Philadelphia-born Gabriel Rosado, who has a reputation as a blood and guts warrior befitting the Philly fighter reputation, while Stitch the cutman is Jacob 'Stitch' Duran as himself, who is the most highly-regarded cutmen of his generation in both boxing and MMA. For what it's worth, Ward and Duran are locks as future Hall of Famers, so Stallone really outdid himself in casting experts. He even cast the real-life Elvis Grant as himself when talking up the Grant boxing gloves that are used in the entire movie. Stallone is truly a hardcore boxing fan.
- Creator Breakdown: Just as the film was entering pre-production, Sylvester Stallone's oldest son Sage died of a heart attack. Stallone has admitted that the loss almost sent him into a full breakdown, but Coogler was eventually able to convince him to use the film as a dedication to Sage, focusing specifically on the father-son relationships that appear in it. Although initially resistant, Stallone said at the Golden Globes that Creed helped him cope with Sage's death and produce one of the best films of his career.It took a while. I really didnt want to do it, I swear to you. Its just too painful. Its rough. There is no closure. There is nothing. The wonderful thing about acting is that its a release. I can take some solace in that.
- Hostility on the Set: During filming, Sylvester Stallone had to break up a fight between two other boxers.
- The Other Darrin: Mary Anne Creed was portrayed by Sylvia Meals in Rocky II and IV; Meals passed away in 2011, and here the character is portrayed by Phylicia Rashad.
- Promoted Fanboy: Tony Bellew, the real life boxing champion who plays Pretty Boy Ricky Conlan, is a lifetime fan of the Rocky films and Sylvester Stallone.
- Reality Subtext: Much like the first film and Balboa, this one heavily reflects the circumstances under which it was made, in this case Stallone finally handing the reins of the franchise he created and has nurtured for forty years over to a fresh new talent who can help it stay alive by taking it in a new direction. And just like Balboa, few people took the film seriously when it was first announced, but after being released it scored even better reviews and is now considered a fully worthy continuation of the franchise, with Adonis having the potential to carry several more films.
- Separated-at-Birth Casting: Quite a few reviewers commented that Michael B. Jordan actually does look like he could be Carl Weathers's son.
- Star-Making Role: For Michael B. Jordan (although he was already known from Friday Night Lights, Chronicle and Fruitvale Station), who had quickly recovered from the colossal failure that his last film was.
- What Could Have Been: There were early plans to include Apollo Creed's trainer Duke in the film. Sadly, Duke's actor Tony Burton's health was failing at the time of filming and he passed away only three months after the film's release.
