Australian actress Rose Byrne will star opposite Patrick Wilson (Watchmen) in Saw director James Wan’s new frightener Insidious (formerly titled The Further). The film is scripted by go-to Wan collaborator Leigh Whannell (Saw 1-3).

Insidious centers on a married couple (Byrne, Wilson) that discovers that the body of their comatose son is hosting evil spirits. Paranormal Activity’s Oren Peli and Jason Blum are attached as producers.

Byrne’s horror/sci-fi creds include Knowing, 28 Weeks Later, Sunshine, and Star Wars: Attack of the Clones (she played Queen Amidala’s handmaiden Dorme). The 30-year-old starlet is best known for her current role as Ellen Parsons on the Emmy award-winning FX show “Damages.”
