- Actor Allusion:
- Kevin Pollak is a stand-up comedian in real-life, so it's no surprise that Moishe is the one most interested in actually hearing Midge's act when she reveals her job to the family.
- To fans acquainted with Tony Shalhoub, the scene in episode 5 where Abe is obsessive-compulsive about the state of the Steiner Resort rec room's shuffleboard seems like something right out of Monk.
- Deecy, one of the girls in Susie's cabin at Steiner Mountain Resort, is a singer and mentions that she's got a singing career coming up. Laura Dreyfuss, who plays Deecy, was Madison McCarthy on the sixth season of Glee, and was Zoe Murphy in the original Broadway production of Dear Evan Hansen.
- Ascended Extra: According to Amy Sherman-Palladino, Luke Kirby was initially only supposed to appear as Lenny in the pilot, but she was so impressed by his chemistry with Rachel Brosnahan that she ended up making Lenny a recurring character.
- Awesome, Dear Boy: Marin Hinkle accepted the role of Rose Weissman because the character was described as "entering the room like she was in a MGM musical".
- Fake Nationality: or more precise fake ethnicity. Neither Rachel Brosnahan nor Tony Shalhoub are Jewish. Both are also from the Midwest.
- Non-Singing Voice: Shys actor, LeRoy McClain, doesnt do his singing, its instead done by Darius de Haas.
- Real Life Writes the Plot: The reason for Noah's new beard in season 3 is that Will Brill had to grow it out for his role as Ali Hakim in the 2019 revival of Oklahoma!.
- Star-Making Role: Rachel Brosnahan was previously only known for a small recurring role in House of Cards (US). The Marvelous Mrs. Maisel is her first starring role and catapulted her into instant stardom.
- Throw It In!: One of the dancers at Midge's wedding (who she reveals were actually hired professionals) drops his yarmulke during his performance, but he simply scoops it up as he finishes. This is clearly a gaffe by the dancer, but it works in-universe.
- Word of Saint Paul: Lead actress Rachel Brosnahan has somewhat infamously said that the very popular Lenny/Midge pairing will not happen on the show because she disliked the idea and requested that Amy Sherman-Palladino keep the relationship platonic. Therefore, depending on whether or not Sherman-Palladino decides to keep to this after season 3, the events of 3x05 (where Lenny and Midge go on a date and then intentionally leave their relationship open-ended) were either a Flip-Flop of God or an instance of particularly cruel Ship Tease that will never get any payoff. Notably, Brosnahan's comments directly conflict with the show's marketing, which seems designed to suggest that there is a chance of the pair getting together.
