I just finished watching this. For the - I think? - fourth time. Each time I watch it, I like it a bit more. The first time I watched it, I just thought the 'macho pose' factor, and the final scene - gunfight on the Sherman corral - were just too much. More on this particular episode later.
And despite the über machismo caveat, the cast in this film are actually pretty good, giving good performances. Watching the extras on the DVD one realises that meeting real WWII veterans, and going to movie 'bootcamp', with genuine military guys on hand to train them, all had salutary and useful effects on the actors. And I think these things help make Fury better than it might, at first glance, appear to be.
Two major themes that resonate most compellingly within the film are: the struggle between the degrading animalistic violence of war, and our more civilised compassionate side; and the family like bonds that develop under such extremes of duress. Don 'Wardaddy' Collier is, both literally and metaphorically, the father figure in the tank (and the tank is the family home!). He dishes out tough love, but he earns the respect and loyalty of his crew.
 Having said this, I learned, during my online research for this review, that the nickname 'Wardaddy' was in fact the real nickname of a U.S. tank commander. And the 'real' Wardaddy, one Lafayette G. Pool, was indeed a Texan (he even allegedly wore cowboy boots in preference to army issue boots!).
 Here's a short movie about Tiger 131's involvement in the filming of Fury.
 Betts also recalled, in relation to the scene showing the execution of a german POW, disarming a 55 year old member of the Volksturm, only to learn later that he was shot. Read the full article here.
