BBC, Ancient Rome: The Rise and Fall of an Empire, Hannibal episode (BBC DVD, 2006) Inaccurate and incomprehensible in places – nevertheless good fun for a Friday afternoon. Superb resource for ‘checking the accuracy’.
BBC, On Hannibal’s Trail
Unfortunately, this is unavailable to purchase – but clips and episodes can be found online. Excellent documentary covering the entire unit. Highly recommended.
