At the beginning of this month I bought the special director’s cut of the Michael Mann film Collateral. I don’t usually buy movies, having learned from past experience that it makes more sense to rent them. But every rule should have exceptions; and it is a good thing to collect those movies that transport you to a specific place or mood. And when you recall the mood, you revisit certain pleasurable sensations. There is just something about the way Collateral is shot, the way it glimmers, that gives it a cool but intense patina.
