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: The voice of Onizuka in the English dub of the series is provided by Steve Blum. However, he had to use an alias ("David Lucas") due to the show being a non-union job. Blum has since jokingly denied that he and Lucas are the same person, despite it being a well-known fact that they are.
Batman VS Iron Man (DC VS Marvel) - S4-E10

Kiseki no fukkatsu! Yuyo no cosmo - S1-E5
Trivia: When Seiya falls down during the victory celebration and the three kids scream (the shot that comes before the one where Miho drops the picture) you can see briefly in the audience between the kids an easter egg appearance of Magical Princess Minky Momo, a character from a different anime. (00:13:50)

Trivia: Daily Mail journalist Frederick McKenzie takes a photo of the Righteous Army, which is stated to be the only existing photo of Korea's freedom fighters. This photo is a direct recreation of a real-life photo of the Righteous Army, taken by Frederick McKenzie (who was a real-life war journalist) and is to date, the only existing photo of Korea's freedom fighters. (00:30:12)
Trivia: Dio in this episode drinks Cronenberg Whisky, just like in the manga. The fictional brand is most likely a homage to the director David Cronenberg, especially given the bit of 'body horror' appearing in this arc.
A Little Bit of England - S2-E13
Trivia: Although they play father and daughter in this episode, Ernie Hudson is only eleven years older than Sheryl Lee Ralph.

Trivia: **SPOILERS** When the demon takes over Ciri's body she dreams about being back at the party her grandmother had at their castle, and she sees her grandmother, Mousesack, her mother and her father. When she starts to question if it's really her grandmother, Mousesack and her mother all turn to ash and blow away. If you pay attention, you'll notice that her father does not turn to ash which is a foreshadow for later when it's revealed that he is in fact still alive.
Tough Luck - S2-E31
Trivia: One of the applicants in Finn's audition is an obvious pun on martial arts legend Bruce Lee. As a matter of fact, the real-life Jackie Chan used to be Lee's stunt double in Fists of Fury and Enter The Dragon.
Crisis on Infinite Earths: Part Two - S1-E9
Trivia: The version of Batman played by famous Bat-voice Kevin Conroy is a darker version of that from the graphic novel The Dark Knight Returns. The line "the world only makes sense when you force it to" is a version of a line from that comic (also used in Batman V Superman), also "Clark always said yes to anything with a badge or a flag." There are also elements from Batman Beyond, which first aired in 1999 (hence Earth-99), in which Conroy voiced an older Bruce Wayne mentoring a new Batman. The whole scene is full of nods to other versions - describing Kryptonite as "a little souvenir from the old hometown" is a Lex Luthor line from the original Superman movie, and him describing Superman as "strange visitor from another planet, with powers and abilities far beyond those of mortal men" comes from Superman serials from the 40s and 50s.
Trivia: Lars Mikkelsen, who plays Grand Admiral Thrawn and voiced him in Star Wars: Rebels, is the older brother of Mads Mikkelsen, who played Galen Erso in Rogue One: A Star Wars Story.
Trivia: The unused script of the final fight between Ultraman and Zetton was entirely different, as it shows Zetton ripping apart Ultraman's colour timer. In the end, Zoffy will save Ultraman and defeat Zetton. However, the writing team decided not to use it because it was deemed too violent, and it portrayed Ultraman, the main hero, being cut. This alternate ending can also be seen in the game Ultraman Fighting Evolution 3 during the Ultraman vs Zetton mission.
The Guardian - S1-E5
Trivia: Stan Lee makes a cameo describing the Division's operative as being like a superhero. (00:07:00)
