Starring: Lucy Hale, Ashley Benson, Sasha Pieterse, Shay Mitchell
Character mistake: When Allison falls down the stairs her fiancé says "EMILY!"
Suggested correction: He shouts "Ali", short for Allison, not Emily.
Suggested correction: He shouts, "Ali" which is short for Allison.
Continuity mistake: On the video of Ian supposedly killing Alison, we see her arm fall to the ground with her "Alison" bracelet visible. But in a later scene where Emily watches Ian put his bag in the athletics room, we cut back to the video and Alison's arm suddenly has a sleeve covering up her bracelet. When we see the video again later in the series, her bracelet is visible again.
Trivia: Lesley Fera, who plays the mother of Torrey DeVitto and Troian Bellisario in this series, is, in reality, only 12 years older than DeVitto and 13 years older than Bellisario.
