In 1964, Jan Spáta created his documentary called Nejvetsí prání (1964), an enquette about the desires of the young generation. It was a time of political liberalization in Czechoslovakia and thus also a time of beautiful visons and desires. In 1969, the film was banned. Jan Spata came back to his "Greatest Wish" in 1990 and created a feature documentary comparing that period with the 1989 events. He even found some people interviewed in 1964 and asked them to speak again, now being 25 years older.
