Oh, I adore Isaacs, too, and that film rates a 9/10 from me. Yet those accents detracted from the film a bit. I just kept wondering why half the American forces were comprised of British soldiers, LOL!
There were a bunch... I was almost expecting Ewan McGregor to play more than one character like Sellers in Dr. Strangelove. That dude was in about every movie from 1999 to 2009.
