Definitely watching it for the tanks. I remember watching "A Bridge too far" and wondering what German WW2 tank those Leopard I were supposed to represent. This was awkward.
Still I can´t help the feeling that the movie is going to have some frustrating stereotype shit in it.
The Tiger will of course lose to the Sherman. Choose one of the following:
1) The Germans get cocky and do something stupid.
2) Brad Pitt does a sacrifice to kill himself and the Tiger.
3) Brad Pitt has a super intelligent plan that would never work, but does work.
4) The Sherman just breaks the law of physics and destroys the Tiger without problems.
In "Saving Private Ryan" - also directed by Spielberg - socks were sufficient to get rid of one of the Tigers.
Either way... the Tiger won´t make it out alive in that movie.
