Sarah Bolger and Sarah Gadon have joined the cast of Mary Harron’s The Moth Diaries, according to The Hollywood Reporter. Bolger and Gadon join the already-attached Lily Cole and Scott Speedman.
Based on the 2003 Rachel Klein novel, The Moth Diaries tells the story of a mentally ill student at an all-girl boarding school. Bolger will play the girl (unnamed in the original text) with Cole and Gadon as two of her friends. Though the specific roles are not listed, Gadon is likely playing Lucy Blake, the protagonist’s roommate, with Cole as Ernessa, a mysterious friend to Blake who Bolger’s character begins to suspect may be a vampire. Speedman, meanwhile, is confirmed to play a professor that Bolger’s character develops a crush on.
Harron is best known for American Psycho, the 2000 film adaptation of Bret Easton Ellis’ novel. Similar to The Moth Diaries, American Psycho‘s original text featured a mentally troubled first person narrator.
