On Scripted vs Ad-libbed or Improvised in re Full Frontal and the President of the United States

This weekend, after seeing Full Frontal, we discussed the dialogue at length. My (grew-up-on-the-stage) wife spotted a lot of weak improv, or weakly directed improv–actors left to figure it out for themselves and, more often than not, not pulling it off. Besotted Soderbergher that I am (nothing like three DVD commentaries in the last two weeks to make you feel like you know the director.), I’d argued that surely Soderbergh knew what’s up; he’s shooting a script that’s written to sound like this. It’s all artificial, after all. Get it?
Rather than address the fact that I was just wrong [Fine. I’ll address it. Nerve.com has an excerpt of the script which differs notably from the scene in the movie. The actors seem to have recreated and expanded on the type of conversation written in the script. A FoxNews interview with Blair Underwood settles on “workshop” as the best way to describe the film.], I’d rather deflect the whole issue toward something “serious.” Here’s Joel Klein in a New Yorker column about Hilary Clinton’s strong showing at that Democratic meeting in NYC last week:

But political deftness and ease of delivery were not the most impressive things about the Senator’s turn: Clinton was the only speaker who didn’t make an advance text available to the press. Apparently, she winged it. A day later, in response to a call to the Senator’s office requesting a copy of the speech, a press aide said, “Sorry, but it’s still being transcribed.”

Don’t contrast this with the seemingly adlibbed (and immediate Moment of Zen) George Bush comment I mentioned yesterday. Contrast it with the most distracting thing about listening to Bush read his speeches, the way he always pauses at what seem to be linebreaks on his index cards. It’s almost like listening to Christopher Reeves on a respirator or to a lighthouse keeper who’s conditioned to pause every five seconds, whether the foghorn’s on or not. I mentioned this several months ago to a friend with very close ties to the Bush speechwriters, but I haven’t been detained yet. All the same, I couldn’t find any articles online talking about this Cageian Bushism. Am I the only one who hears this bomb’s tic?
