I reckon there are only four films I've seen more than once, properly, all the way through, Breakfast at Tiffany's, The Lion King, Lord of the Rings and Heat. Breakfast at Tiffany's used to be my favourite film but now I think it's Heat.
One of the things I love about it is the attention to colour. Almost everything in the film is cold steely blue colour. Sure, it's easy enough alter the grading but they've also used blue lights, blue clothes, the sky and the sea. All to add to the subtle blue effect.
It was on telly last night so I tried to take some pictures to prove my point. You can't really see what I mean because the tungsten lighting of my lounge alters the colours. But there are some more pics on Flickr if you're interested.
