The second time a genuine Tiger I tank has been used in the production of a WWII film. It features "Tiger 131" from the UK's Bovington Tank Museum, the only fully functioning Tiger I tank in the world.

The cast underwent a rigorous month-long course. The final test was manning a real tank during a combat exercise. Brad Pitt, who was much older than his cast mates, made sure that he participated in all of the physical training alongside the other actors.
