History Trivia / PrettyLittleLiars

** Creator/SashaPieterse was 12 when she did the pilot episode and 13 when she filmed season 1 playing 15 year old Alison. To be fair, nobody could tell.

* HeyItsThatPlace: It was shot on the same WB set as ''Series/PushingDaisies'' and ''{{Shameless}}''. If one's seen both shows, it's easy to point out the set used for Radley was in ''Pushing Daisies'', and if you look closely in certain street shots, you can point out the Alabi Room.

* IKnewIt: [[spoiler: Nate killed Maya]]
** [[spoiler: Creepy weirdo Toby is part of the A-Team]]
** So many fans suspected [[spoiler: 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 [[spoiler: [[SubvertedTrope subverted]] that, by revealing Mona is actually alive]].
** [[spoiler: "A"/Charles being a transwoman]] was considered one of the more out-there theories after it sprouted up during the sixth season. And then it happened. Weirdly, a lot of proponents of the theory failed to correctly guess ''which'' [[spoiler: woman Charles would turn out to have become, even though CeCe, a character whose primary character trait is her resemblance to Alison, was the most obvious candidate]].
** [[spoiler:Emily's stolen eggs]] and [[spoiler:Alison's pregnancy]] are connected.
** AD is [[spoiler: Spencer's long lost twin sister, '''A'''lex '''D'''rake]].

** TheCastShowoff: Janel Parrish bursts into a bit of Music/SaraBareilles' "Gravity" in "A Dark Ali." And in "Driving Miss Crazy" [[spoiler: she gets ''a entire production number'' doing "Jailhouse Rock" during a dream Aria is having, [[ButYouWereThereAndYouAndYou with Mona as a guard and Veronica Hastings as the warden]] officiating Aria's wedding in a prison to a freshly beaten up Ezra]].

* WritingByTheSeatOfYourPants: Even though show runner I. Marlene King has repeatedly confirmed to have known who A, other A and AD were all along (or at least from mid-Season 3) the immense amount of plotholes one can discover once one re-watches the series knowing already who will be revealed as A(s) makes one think that Marlene was practically just winging it in the writer's room for seven seasons straight and when it came to a season finale and it was time to reveal somebody as A, she just drew a name out of a hat.

** Averted with Alison. Creator/SashaPieterse 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.

** 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 [[Film/SpringBreakers Spring Break]]."
