Rita Volk originally auditioned for Karma but ended up getting the role of Amy.
In Faking It, Amy wasn't originally written to have feelings for Karma, but the showrunner knew that the show would come off as offensive, so they made Amy fall for her.
In Season 2 Episode 9, Amy jokingly says Liam (Gregg Sulkin) is a werewolf. Before being casted in Faking It, Gregg Sulkin had a reoccurring role in Disney's Wizards of Waverly Place (2007) in which he played a werewolf.
Shane makes a reference to Flowers in the Attic. Costar Bailey De Young had a role in Petals on the Wind (2014), part of the Flowers in the Attic series.
Greg Sulkin (Liam), Lindsey Shaw (Sasha) and Chloe Brighes (Zita) all guest starred on the show Pretty Little Liars (2010)
