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.
About shooting in Oxfordshire, England, Brad Pitt said, "No rations, no showers, and we were sleeping in the rain. It was miserable, but we loved it".
During filming, Shia LaBeouf almost got in a real fight with Scott Eastwood while the cameras were rolling. Eastwood, riding on the back, kept spitting tobacco juice onto the tank. LaBeouf felt this was disrespectful, and exchanged words with Eastwood. Things got heated until LaBeouf found out the script called for Eastwood's character to spit his tobacco juice onto the tank. Per Eastwood, Brad Pitt had to break up the fight.
