"I tell you, there was never a trip like this before. The motives are terribly sad, but we are going to have a lot of fun. This is another dimension of history." With these words, Arnost Lustig and Jan Wiener, both Jewish survivors of the Shoah, embark on a trip to the Europe of their childhoods, documented in the film "Fighter." Premiering at the Los Angeles Independent Film Festival, "Fighter" is a unique exploration of both the Holocaust and the Communist era of Eastern Europe.
