I'd like to say that I thought Layer Cake was brilliant. Especially when the Russian assassin guy calls up Daniel Craig to threaten him... (paraphrase warning!)
Daniel Craig: Hey, let's talk about it like reasonable men. How about you come over for breakfast, I'll make some orange juice...
Russian Assassin: Very civilised of you.
DC: Do you know where I live?
DC: Well fuck off then! *slams down phone*
