She appeared in her first big film: the remake of the classic film, The Amityville Horror, in 2005. At the time of the film’s release, she was so young that she was not allowed to see it with the rest of the cast at the film’s premiere. Her biggest break came in 2010, when she took on the controversial role of Mindy Macready, aka Hit-Girl, in Matthew Vaughn’s film adaptation of Mark Millar’s popular graphic novel series, Kick-Ass. Thanks to her intense training for the film, Chloë is trained in martial arts and weapons handling.
