Screenterrier reported back in 2009 and 2010 on the casting of Lily Cole as Ernessa and Sarah Bolger as Rebecca in director Mary Harron's feature film adaptation of Rachel Klein's cult teenage gothic novel The Moth Diaries. They are joined by Canadian actress Sarah Gadon as Lucy.
Check out the trailer and official synopsis below:
Adolescence is and always will be a time of intense emotional confusion, especially if you spend it in a closed environment. That’s the case with Rebecca, a young girl haunted by her father’s suicide, who is a student at an exclusive female boarding school. She pours her heart out in a diary, much of it focused on Lucy, her beloved roommate. Their relationship changes drastically with the arrival of a mysterious new student, Ernessa. As Lucy abandons her for this new girl, Rebecca becomes consumed with thoughts of jealousy and suspicion — Ernessa is dangerous, evil, a vampire. Is there any truth to all this or is Rebecca slipping into insanity?
