Jazz blanco
Carnahan described his vision of "White Jazz" as reflecting the "kind of mid-century explosion of art and music, and really letting that be the kind of guiding force behind it, as opposed to making it like this ... all 'period suits'. I really want to try to make it as accurate a reflection of L.A. at that moment in time as I can." He also commented on George Clooney's willingness to play an unlikable character for the first time. "He's made that very clear to me: 'I have no other desire than to play what's in that script.' And what's in that script is a pretty despicable guy at times, and pretty nefarious and nasty and selfish." Carnahan also touched upon how he trimmed down the novel's numerous subplots because "I always thought that as much as I love "White Jazz", it became almost unfilmable at some point, because there are so many strands, so much, and it became so psychotic ... that's what made it such a great book, but those things would not carry over into the filmic realm, I thought, with ease."
