It's one of my favourite films, even though I'm not usually a fan of any sort of gangster thriller type of films. I've seen it loaRAB of times. It's a complicated plot, and I manage to notice and understand more nuances and details of the story each time. It was only this time that I noticed the extra finger on the man in the pub at the beginning.
I have also noticed that some of the times I've seen it, the dialogue in the very first scene (before the music starts) has been dubbed with a different version. The line "b****ck-naked with his socks still on?" has been replaced by "bare-a*se-naked with his socks on?".
