Layer Cake (2004)

Itching for more Daniel Craig after Casino Royale? Netflix
this sucker ASAP. It's a British gangland movie in the spirit of Guy
Ritchie (Lock Stock/Snatch), which isn't surprising
since Matthew Vaughn, the director, produced those two films, and
Layer Cake has the same cast of tens and labyrinthine
underground-drug-trade plot.

What makes this movie MUCH better than those two are Vaughn's
eschewing hyperactive camera tricks for character development, and
Daniel Craig again getting to be a badass with a gun. This time,
though, he's a middleman trader who has never used a gun, which makes
his entry into the violent side of his business sort of like James
Bond becoming a 00-status agent. There's even a hilarious moment when
a friend gives him a gun and Craig's character starts skulking down
the halls of the apartment, stone-faced, hunting down some imaginary
terrorist -- I mean, druglord -- trying to kill him.

So there you go. Layer Cake is a prequel to Casino
Royale, whether or not the filmmakers knew it at the time.
