EXCLUSIVE: Canadian actress Sarah Gadon has landed the female lead in The 9th Life Of Louis Drax, the adaptation of Liz Jensen’s best selling novel that Alexandre Aja (Horns) is directing for Miramax. The thriller centers on Louis Drax, a young boy who suffers a near-fatal fall on his ninth birthday. A psychologist probing into the accident is drawn into a mystery that tests the boundaries of fantasy and reality. Gadon has emerged in recent years with striking back-to-back roles in Brandon Cronenberg’s Antiviral and David Cronenberg’s Cosmopolis, and won the role of Louis’ mother Natalie in a competitive casting search. She’ll star opposite Fifty Shades of Grey‘s Jamie Dornan as Dr. Allan Pascal and Breaking Bad‘s Aaron Paul, who is set to play the boy’s father.

Gadon also recently appeared in Enemy, Belle, and the animated feature The Nut Job and next stars opposite Luke Evans in Universal’s horror actioner Dracula Untold. She recently filmed Girls’ Night Out for Julian Jerrold and The Girl King for Mika Kaurismäki, and stars again for David Cronenberg in his Hollywood-skewering Maps to the Stars. She’s repped by WME and Creative Drive Artists.

The 9th Life of Louis Drax was adapted by actor Max Minghella in his screenwriting debut. Minghella is also producing alongside Tim Bricknell (The No. 1 Ladies’ Detective Agency, Breaking And Entering) of Antcolony Films, Shawn Williamson (The Interview, 50/50) of Brightlight Pictures, and Aja. Rosanne Korenberg (Half Nelson, Hard Candy) is executive producing. Miramax EVP Zanne Devine is overseeing for the studio and Sierra/Affinity is handling international sales. Filming is set to begin next month in Vancouver.
