Brad Pitt stars in Marc Forster's adaptation of Max Brooks's post-apocalyptic horror novel, which follows a UN employee's struggle to prevent a zombie pandemic from destroying humanity.
James Badge Dale, Mireille Enos and Matthew Fox are among the supporting cast.
Matthew Michael Carnahan (State of Play), Drew Goddard (The Cabin in the Woods) and Damon Lindelof all worked on the script, with Lindelof being brought in to rework key scenes after principal photography had already wrapped.
Pitt has suggested that an early cut of the film was "too political" and became bogged down in a serious message.
