After watching the trailer for Oliver Stone’s W. a few weeks ago, I had the impression that the George W. Bush biopic wasn’t going to be an impersonation fest. Of course, we only really got to hear James Cromwell as George H.W. Bush, and he didn’t seem to be bothering to sound like anything other than himself — not that I was expecting him to do Dana Carvey doing the senior Bush, but a bit of a change in voice, in order to make me not feel I’m watching the junior Bush getting yelled at by L.A. Confidential’s Captain Smith, would have been appreciated.

Fortunately, as we can now see in some new behind the scenes footage courtesy of Access Hollywood, Josh Brolin is making an effort to sound like the man he’s portraying. Maybe it’s not so perfect that he’s mistakable for the real deal when you listen to the audio alone, but at least he doesn’t just sound like Josh Brolin, either. The video also gives us additional glimpses of Toby Jones as Karl Rove and Elizabeth Banks as Laura Bush. The latter can be seen studying actual footage of the President (and likely the First Lady) and practicing mannerisms, and thankfully providing a tiny bit of playfulness to an otherwise too-serious looking set.

Now, when do we get to hear Banks speak? And, for that matter, when do I get my anticipated impersonations of Condi, Colin, Karl, Don and Dick?
