There's no subs, so I'll translate the things written out:
Andrew G. Vajna presents ... On the streets of Budapest ... At the Olympic games of Melbourne ... Revolution breaks out ... Szabadság Szerelem (the title)
Szabadség Szerelem is a Hungarian movie about the revolution of 1956 against the Soviet Occupation.
(this is rather a poorly cut trailer, I'll also link the original)
I totally got into revolutionary songs. :D This is Rakoczi March. Rakoczi War of Independence took place from 1703-11 in Hungary. It was uprising against the Habsburgs.
