'9' is a 2005 CG-animated short film written and directed by Shane Acker while a student at UCLA, produced in part with the assistance of Tim Burton. The 11-minute piece introduces a sentient burlap doll, numbered 9, who wakes in a ruined workshop in a post-apocalyptic world stalked by the mechanical Cat Beast and seeks out the eight earlier-numbered dolls created by the same Scientist. Burton and Timur Bekmambetov produced the 2009 feature-length expansion, with Acker returning to direct and Elijah Wood voicing the title role.
