Having seen the trailer, I have to say, it looks beautiful in colour and cinematic depth. The sheer scale of production is conveyed in the trailer, with some superb settings and switching of colour pallets. It is almost Heat and Collateral mixed together, with night and day intermingled through the trailer, each with blazing effect. There will be much written about this trailer, but don't waste any more time reading this - go watch it!
My verdict: Looks superb. What else would you expect from Michael Mann? The trailer starts slow and ramps up more dramatically towards the end. I think I can see where the next cinematography oscar is going already! Johnny Depp looks convincing too.
