Groundbreaking 3D graphics and state-of-the-art computer animation provide some of the highlights in this authoritative and entertaining look at Hitler s siege guns of World War Two. The programme also features extraordinary archive footage obtained from German and Allied sources and an all-new look at surviving examples of German heavy artillery. Among a team of eminent military authorities who help to tell the fascinating tale behind such monster weapons as Anzio Annie and the mighty Thor, are Dr William Atwater - curator of the US Army Ordnance Museum in Washington, and author and historian Bob Carruthers.
