The first time Daniel Craig is handed a gun in “Layer Cake” (2005), he briefly prances around like he’s 007 or something. That would still be a year or so away. We get to see him command a stage while on the wrong side of the law in this classic British gangster flick. There’s a much-coveted shipment of drugs and lots of double-crossing, just like in most gangster flicks, including the bad ones. The good ones let you follow along just closely enough to think you know what’s going on, when you really, really, don’t. This is a good one.
