Kelly Reilly Goes For Blood & Joins ‘Innocence’
Kelly Reilly has joined the Hilary Brougher-directed vampire film Innocence, adopted from Jane Mendelsohn’s 2000 teen novel with a screenplay by Tristine Skyler. Innocence centers on a moody teenager who discovers her elite private school is home to a vampire gang. Reilly, who appears in the Sherlock Holmes franchise as Dr. Watson’s wife Mary and recently wrapped Robert Zemeckis’ Flight with Denzel Washington, plays a school nurse with a dark side. The film is produced by Christine Vachon and Pamela Koffler’s Killer Films along with Bankside Films. Reilly is repped by ICM and by Troika in the UK.
In other Kelly Reilly movie related news, she has two more upcoming films slated for 2013 with one she's currently filming: A Single Shot (with Melissa Leo, Sam Rockwell, and William H. Macy) and another that's on pre-production: Calvary. No theatrical release date yet on her Flight film (with Denzel Washington, Melissa Leo, and John Goodman).
Kelly Reilly is currently seen on TV in the UK in ITV's Above Suspicion: Silent Scream (TV series) as DI Anna Travis, which she co-stars Ciaran Hinds (Persuasion 95's Captain Wentworth).
