I was on "Vítejte v KLDR!" ("Welcome to North Korea!") yesterday and I really enjoyed it somehow. It does more or less present the reality of state where comunism was "succesful". While the whole cinema was laughing several times, I have seen much similarity with Orwell's 1984. Worth visit (cinemas Aero and Světozor), probably soon on HBO (as HBO is one of partners). You can practise your Czech, English, Russian and Korean.
