"Green Room's" Imogen Poots has joined the cast of "I Kill Giants," based on the Image Comics series by Joe Kelly and J.M. Ken Niimura.
The 2008 comic follows Barbara Thorson, an outcast fifth-grader who must deal with real-world problems in addition to an impending (and possibly imagined) onslaught of giants she's convinced she must combat.
Zoe Saldana signed on last year to play Ms. Molle, a school psychologist, while 13-year-old Madison Wolfe ("The Conjuring 2") is set to star as Barbara. Poots' role wasn't specified by Variety, but it's possible she could play Sophia, who befriends Barbara in the comic.
Poots made her big-screen debut in "V For Vendetta" before going on to appear in such films as "28 Weeks Later," "Fright Night" and "Need For Speed."
Produced by Chris Columbus, and directed by Anders Walter from a script by Kelly, "I Kill Giants" is expected to begin filming Sept. 27 in Ireland and Belgium. No release date has been announced.
