From the video's description:
Bloody omaha was created by Colin Thornton, Neil Wilson and Steven Flynn who run the graphics company Compost Creatuve . www.Compostcreative.com
The music used Is Two Tribes by Frankie goes to Hollywood.
Team Compost headed out to Omaha Beach for 4 days armed with a Z1 camera, a pop up greenscreen, some soldier uniforms and 2 rubber rifles (we couldnt afford 3), and begun the process of covering the beach (with camera on the cliff top), and re-enacting the veterans moving accounts. When back in London (and back in our real day job) we began to piece together all wed shot using adobe after effects, (and a little 3d modelling in maya) turning the 3 of us into the invading U.S. army.
6 Weeks later the work was completed and provides a moving insight to the U.S veterans memories of storming Omaha beach, for BBC 2's Timewatch: Bloody Omaha.
