Alan Berliner's Intimate Stranger was a spirited look at his mysterious grandfather. In Nobody's Business, he takes on his father. Son of Jewish immigrants, Oscar Berliner was a perfect 1940s man: a stolid, hardworking, honorable guy who fit in best with his World War II Army buddies. Then he married glamorous, exotic aspiring actress Regina, with whom he was classically ill-matched. Now he is long divorced and retired into a bitter, reclusive old age. Home movie and found footage wryly punctuate the quasi-Oedipal duel between the stoic, clam-like father and his stubborn, prying son.
