Louie/Trivia

Ability Over Appearance: Louie's ex-wife, Janet is played by African American Susan Kelechi Watson; Louis has even confirmed that he chose the actress not only because it humorously ignores how they have completely Caucasian children, but because he felt her being perfect for the role took priority. Confusing matters further, in a flashback in "Elevator Part 4", she's played by a white actress.
- Lampshaded in "Pamela Part 3" when the title character asks about the kids; Janet's mother is white. Pamela does not accept the explanation.
Actor Allusion: Louie plays a cop in a The Godfather sequel, like he did in Parks and Recreation.
- Alcoholic, drug addicted, bitter comedian Doug Stanhope guest stars as Eddie Mack, an alcoholic, drug addicted, bitter comedian.
The Cast Showoff: The Season 3 episode "Dad" opens with a minute-long sequence of Ursula Parker, the little girl who plays Louie's younger daughter Jane, flawlessly playing the violin. Of course the music is cut off by Louie yanking the instrument out of her hands and yelling at her to go do her homework. That same episode, Parker shows off her fluency in Slovenian.
The Danza: Pamela Adlon's character is named Pamela (unlike other characters in the show, she doesn't seem to be just a fictionalized version of the actor).
Fake Nationality: Louie's Hungarian neighbor Ivanka is played by Ellen Burstyn.
Hey, It's That Guy!: Amir as a comedy writer who cannot tell a joke.
Write Who You Know: Louie regularly bases his stand-up material on some incident that occurs in the episode.
