Tyler Perry will star as the title character, a detective who teams up with Edward Burns' character to find a maniacal serial killer. Matthew Fox will play the killer, his first major role since his ABC series Lost went off the air last year.
The movie is said to serve as an origin story for Alex Cross, a character created by novelist James Patterson. Morgan Freeman previously played Alex Cross in the movies Kiss the Girls and Along Came A Spider.
Rob Cohen is directing I, Alex Cross from a screenplay by Marc Moss and Kerry Williamson. Production is slated to begin in August, with Summit planning on a late 2012 or early 2013 theatrical release.
