Thanks for the feedback guys. Want to give Battle Royale and Kontroll a go but have to be in 'the mood' to watch a subtitled film. Enjoyed The Host a while back which was very quirky with a dark sense of humour, and have seen Crouching Tiger, Hidden Dragon a number of times, though not for a while. Oldboy was a terrific experience too - very original and unexpected, but settling down to these foriegn language films requires a certain state of mind.
Based on your comments I'm gonna make Jarhead or The Loved Ones my next choice.
Talking about The Sting I was surprised at how much Robert Redford reminded me of Brad Pitt. His mannerisms and physicality in this film were identical to BP's and I wonder if the latter has modelled himself on RR or if that's just his natural style? Oddly I didn't get this connection from Spy Game but I guess it's the young Redford full of swagger that appears so familiar.
