With the Hunger Games destroyed forever in Mockingjay: Part 1, The Hunger Games: Mockingjay: Part 2 (12A) opens with Katniss Everdeen (Jennifer Lawrence) plotting the final downfall of the evil President Snow (Donald Sutherland) as the rebellion against the repressive government in the Capitol achieves an irresistible momentum. 

Two of the cinema's bad guys - those of the title - meet in the snows of Antarctica to do battle, as they do every hundred or so years.
