Trivia: Pretty Little Liars

  • Actor Allusion:
    • Emily and her mom are discussing Aria's hair in the pilot when this line comes up
    "What kind of mother would I be if I let you run around looking like a goth?"
    • In "What Lies Beneath," Paige mentions that she should have taken wood shop instead of trig. Lindsey Shaw previously played Moze, who was pretty much a wood shop prodigy.
    • The Dolls of the Liars in A's lair are Bratz dolls. Janel Parrish was in the live-action movie.
    • Ashley Benson and Janel Parrish are real-life best friends just like Hanna and Mona
    • In "Love Shack Baby" Hanna tries to turn the music up in the car on a road rip to find Ali. Emily remarks "This is not Spring Break."
      • Hanna also has experience with guns.
    • In "Who's in the Box?", the non-appearing Spencer Expy is named Avery, which happens to be Troian Bellisario's middle name.
    • "The First Secret" has Jenna dress like Lady Gaga. Tammin Sursok previously did so on an episode of Hannah Montana.
  • Adored by the Network: The show is loved by ABC Family so much that it released another series based on novels by Sara Shepard, The Lying Game.
  • Channel Hop: In Britain the first season was shown on Viva very soon after its US debut - but after the midseason break it eventually started from the very beginning on MTV. Unfortunately MTV dropped it after season two, but fortunately for British fans Netflix came to the rescue (as they did for UK followers of Breaking Bad), and the series makes its bow on the service from New Year's Day 2015.
  • Creator-Preferred Adaptation: "Preferred" might be the wrong word, but Sara Shepard, the author of the books, is a big fan of the TV series. In her authors notes, she mentions having regular dinners with Marlene King to discuss the show and she even dedicated "Deadly" to the four leads.
  • The Danza: Sara Shepard plays Miss Shepard, whose first name is probably Sara.
    • Confirmed in the opening of 'I'm A Good Girl, I Am'.
  • Dawson Casting:
    • All four main girls are played by actresses who are between the ages of 20 and 25. Maya is the most egregious example as the character is 16 but the actress, Bianca Lawson, is 31. Bianca Lawson also appeared on Dawson's Creek in 2000 playing a 16 year old at age 20 making her an original Dawson Casting actress.
    • Averted with Alison. Sasha Pieterse was 14 when she was cast. She's now seventeen, but since three years have passed in-story, she's still the same age as Alison.
      • Actually Inverted. She was 12 when she got the pilot.
    • Tammin Sursok, who plays blind high school student Jenna, is 28.
    • Special mention goes to Troian Bellisario born in 1985 who is older than her teacher and her older brother Jason who were both born in 1986.
  • Directed by Cast Member: Chad Lowe (Byron, Aria's dad) directed "Touched By An 'A'-ngel," "Father Knows Best" (appropriately), "Kingdom of the Blind", "That Girl Is Poison," "Hot Water," "Into The Deep," "Who's in the Box?", "She's Come Undone," "Surfing the Aftershocks" and "March of Crimes."
  • Fake American: Samara and Caleb's dad are played by Australians Claire Holt and Bernard Curry, Jenna by South African-born/Australian-raised Tammin Sursok, and Emily by Canadian Shay Mitchell. This is not the case for Alison because while Sasha Pieterse was born in South Africa, she has spent most of her life in the United States.
  • Fan Nickname: Over on Something Awful, the show is affectionately known as Tween Peaks.
  • Hey, It's That Guy!: Piper Halliwell is Aria's mom, Moze is Emily's overly competitive swim teammate and later, girlfriend Paige, and Janel Parrish as Mona. Lucy Hale plays Aria, Kendra is Maya, McGee's sister is Spencer and her sister is Nanny Carrie, and Ryan Merriman is Ian.
  • I Knew It: Nate killed Maya
    • Creepy weirdo Toby is part of the A-Team
    • So many fans suspected Mona would die in the season 5 mid-season finale that they literally started to believe it was too obvious to happen, ending with them being shocked when it did actually happen. Then along came 'Welcome To The Dollhouse' which subverted that, by revealing Mona is actually alive.
  • Lying Creator: Marlene King. She even outright admitted it when asked about why she stated Mona was dead when it was revealed to be false.
  • Natalie Hall (Kate) and Shay Mitchell (Emily) went to the same high school.
  • Shay Mitchell and Ryan Merriman were both born on April 10.
