27 Shocking Secrets about the Pretty Little Liars Cast

Since it came on the air in 2010, Pretty Little Liars has been more than a TV show—it's been an addiction. We can't get enough of the Liars' killer wardrobes, the chemistry between them and their hot beaus, and the insane drama that's been unfolding for four years. And the fandom doesn't mess around—PLL fans film reaction videos for YouTube (that Shay Mitchell confesses to watching!), contribute to a PLL Wiki, and theorize about series-long plot lines. It's taken the world by storm—and there's so much you don't even know! From casting dilemmas to the town that Rosewood's based on, we've dug up the hottest secrets behind the cast and story of Pretty Little Liars.

Ashley suggested the theme song

Ashley Benson suggested using "Secret" by The Pierces as the theme song. As she told AOL TV, "I have to take some credit here, because I was the one who brought that song to the producers and told them 'You have to have this as the opening credits song.' ... It's just so spooky and eerie, and it's perfect for the show."

Keegan Allen (Toby) originally auditioned for the part of Dr. Wren. Thank goodness he ended up playing Toby, because we get much more face time with his abs—we mean, eyes—this way.

Shay Mitchell started modeling in 2008 on Degrassi. She has struggled with body image—how could you not, being a teen in Hollywood? She told Self: "'I'd starve myself for a day, and the next day I was hungry, tired, and miserable. When I felt so bad about not being able to fit into size 0 jeans, I realized I had to make a change.'"

Totally weird fact about the character Emily Fields (played by Shay Mitchell): One of the nicknames her parents have for her (both in the books and on the show) is "Killer." Spooky, right?

Pretty Little...Gilmores?

Apple Rose Grille—the restaurant the Liars frequent—was once Luke's diner on Gilmore Girls. Though we can't bear to think about the fact that Gilmore Girls is no more, we can at least take solace in the fact that parts of it are still there for us.

Hitchcock is a major influence

VIEW ALL

Pretty Little Liars plays homage to Alfred Hitchcock multiple times, including the Noir episode. Says writer Joseph Dougherty in an interview with the Hollywood Reporter: "So much of the visual aspects of Pretty Little Liars comes from a place of respect for classic filmmaking: Hitchcock and the '40s. We're writers who pay back the debts to the writers...that made us turn into writers."

Emily's bi?

Though we're just glad her sexuality is dealt with so maturely and openly on the show, it's worth noting that in the books, Emily is bisexual, not lesbian.

None of the TV Liars looks anything like the character descriptions in Shepard's books. If you haven't read them—Aria has black hair and blue eyes, Hanna has auburn hair and brown eyes, Spencer has dirty blonde hair and green eyes, and Emily is a strawberry blonde with green eyes.
