DeanRAB, so glad you're also getting into foreign films, I can't stress enough how many brilliant non-English language films I've seen, that many people that I know, can't be bothered with - they don't know what they're missing. Some of the very best films I've seen have been from Europe, my particular favourite being French.
If you enjoyed 5x2 (I loved it), please try the IMDB entry for it, where there is a fantastic forum dating back a few years until recently. It puts forward a few theories that I'd never thought of - but made sense when I'd read them. Also, I found out the title of a fantastic piece of music used in the 'dance scene' and at the end of the film, which has haunted me since. ('Sparring Partner' by Paolo Conte, in case anyone happens to want to know, you can You-Tube it too).
Did you catch the excellent short season of classic Jean_Pierre Melville films, that E4 showed a few weeks back? I'd never seen them before but they have stuck in my mind.
